Foreword

1. There are 3 version of X735: V1.0, V2.0, V2.1:

Version 2.1(Updated on Oct. 30th, 2019): Only change jumper 'FAN_HS' to 'AUTO ON' function; because we found 'AUTO ON' function is more useful to user.

Version 2.0(Updated on July, 30th, 2019): special update for raspberry pi 4 model B. Support all current models of the Raspberry Pi using a 40-pin header including pi 4 / 3B+/3B/2B/B+.

Add TYPE C power port for Raspberry pi 4 model B, and replace the 'select button' with L-SW jumper, add the another FAN_HS jumer to enable full speed fan. In fact, X735 v2.0 can have more performance.

Version 1.0:(Released on June, 24th) : designed for raspbery pi 3B+/3B/2B/B+

X735 V2.0 vs X735 V1.0


2.The X735 works seamlessly with the X825/ X828/ X857/ X835/ X872/ X820/ X850/ X830/ X860/ X870/ X852/ X822 to build your NAS storage center. At the same time, considering that you need a matching shell, we also design cases that can support X735.

At this point, you already have a mini linux working host.

Overview

The X735 is a multifunctional expansion board for all current models of the Raspberry Pi using a 40-pin header. It provides intelligent and safe power management, safe shutdown and full poweroff through software, an automatic temperature controlled fan which enables the use of the Raspberry Pi in extreme conditions including very high temperature environments. The X735 also reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications.

At the same time, x735 reserve two kind of 4PIN power switch (momentary switch and latching switch) port, you can connect the additional power switch to safe control the power on/power off;

Important Note

  1. Safe shutdown script: Document
  2. Full power off via software is not supported when using a external latching switch;
  3. "L-SW" Jumper on X735 should be removed when using onboard switch / momentary switch;
  4. "Auto On" Jumper on X735 should be removed when using external switch;
  5. Both "L-SW" & "Auto On" Jumper caps should be removed when using momentary switch;
  6. Support 4 kinds of power supply: Micro USB, Type C, DC5525 port (recommend), 2H5.54. (Do not power the Raspberry Pi via the Raspberry Pi's Micro-USB socket)
  7. Don't use this X735 power mgnt board with other power mgnt board like X725, X750, X705, etc.
  8. When use X735 with X835/X832, please DO NOT power from X735, please power via X835/X832 DC 12V IN PORT.
  9. When use X735 with X825, X828, X829, X857, X856, X855, X820, X850, X872, X862, X860, X870, X822, X852, please power via X735.

FAQ

1.How to use the Auto Power On jumper and Latching Switch Jumper on X735 V2.1 version board?

There two jumpers: Auto Power On jumper and Latching Switch Jumper on X735 board.

  • Auto Power On jumper

Short - Auto power-on when power applied

Open - Power on when power button pressed

  • Latching Switch Jumper

Short - Using external latching switch

Open - Using on-board power button or external external momentary switch

  • 1. When use X735 V2.1 with Geekworm X825-C2 Case, we equipped momentary switch in X825 metal case, please remove both of the jumper caps.
  • 2. As the auto power on function use latching switch, if you need to use auto power on function, please connect an external latching switch to X735 board or use X735 on board power button.


2. Which GPIOs are used in the X735 script?

Answer: The GPIO4, GPIO17 and GPIO18 is used for power management. And the rest GPIO pins are available to use.


3.What if I connect the x820 XH2.54 5v to the IN of the X735, and then connect the power supply to the x820. Will the safe shutdown work?

Answer: This is no suggested, because power supply for X820 cannot be controlled by X735 and safe shutdown won't be implemented as well. You need to power from the X735 5V IN DC port.


4.Does the x735 power board work with the rock64 board? is the 40 pin connector compatible with the rock64 40 pin connector?

Answer: In fact, we didn't test X735 based with ROCK64, and we didn't consider ROCK64 board when we wrote a safe shutdown shell script, so we think X735 is not compatible with ROCK64. Also the PIN definiton of ROCK64 is different with Raspberry Pi. So it is not suggest to use X735 board with ROCK64.


5. What is the pinout for the PWR Switch?

Answer: Please refer to here: PH2.0 Conector Specification


6.Does the X725/X750 support to use with X735 together?

Answer: Please refer to Connecting the X725 UPS to the X735 Power Supply


7.Does the X735 support to check the speed of the fan?

Answer: Sorry, no, it is not support to check the fan speed by software.


8. Why my RPi4 will switched off directly after connected to the X735?

1. Please confirm all product connection is correct first. If you are not sure about the connection, please attach some pictures and contact us for help.

2. Please also do the following test and show us the result.

  • Remove X735 from the Raspberry Pi
  • Connect the power to X735
  • Press the blue button on X735. Does the blue LED light up? Does it turn off automatically?
  • Press and hold for more than 8 seconds, will the blue LED go out?

9.How to remove/unload the X735 script from your Pi?

A: Open the /etc/rc.local file (sudo nano /etc/rc.local or vim /etc/rc.local to open the /etc/rc.local file;), and seach x735, then comment out that line (add # on the begin of that line);

10. Can the x735 work in harmony with the x765 POE?

  • A: Yes, but the X735 must be set as "AUTO ON" mode.

11. Does this supply safe shutdown when power is cut? Or just safe shutdown when power is constant and a signal switch is cut

  • A: Sorry, no, the X735 does not support safe shutdown when power is cut. Please consider X728 if you need this function.

12. How to delete X735 script completely?

  • A:

(1)sudo nano /etc/rc.local , delete "x730pwr.sh", then save

(2)sudo rm /etc/x730pwr.sh

(3) sudo rm /usr/local/bin/x730shutdown.sh

I have the x735 v2.1 working on a pi 4B and I am trying to use the x735 as a power management. Since Pi requires 5V 3A and my monitor requires 5V 2A, I want to provide 5V 6A (fast charging cable) to X735 using USB C, and it provides power to pi though 40 pin and provide power to monitor though 5V out on x735. Does this work? I try to use the usb C for my power supply.

I have the x735 v2.1 working on a Pi 4B running Buster. However it doesn’t work when I plug a HiFiBerry DAC + Pro due to conflicts with GPIO.

The Pi system just halts after the DAC kicks in from the script /etc/x730pwr.sh HiFiBerry states the GPIO18 the sound interface in hardwired on the Pi so it can’t be mapped onto another pin.

GPIO18 is only used for software shut down $ x730off that I’m not going to use Reference script /usr/local/bin/x730shutdown.sh

I have re mapped the GPIO4 and 17 in script /etc/x730pwr.sh and still no good so it must be down to the GPIO of the x735 being activated from the DAC!!

Question is has anybody else managed to get the x735 v2.1 working with a HiFiBerry DAC + Pro?

Or do I get another Power Management Unit? Or a different DAC?

Or dump the PM Unit idea altogether?

Before using the X735 v2.1 I plunged it into a working Pi4B. Using the momentary power button(external one and nothing so used the PCB button), no jumpers connected, no PSU connected to the Pi, it behaves like this:- 1 Pressing power button Pi powered up, fan and lights on X735 on Pi good. 2 Pressing the power button 1 to 2 secs nothing, no flashing LED's and no action. 3 Pressing the power button 3 to 4 secs all powered off Pi and X735 as if I had pulled the plug and no flashing LEDs

I don't need software power off so no need for x730.sh

Do I need to do something else to get it to work properly?

I bought two x828 boards and a x735 board for my raspberry pi 4 to connect two hard disks, a Samsung evo 860 (SSD) and a Seagate barracuda (HDD).

I've followed the instructions in the videos to assemble all boards with the raspberry and disks and everything works properly except when I want to reboot the system with the command: sudo reboot. The system shuts down but but it doesn't restart and I have to unplug the power adapter to reboot the system.

I've tried the raspberry only with x735 and works fine and reboot is ok. And i've also tried the raspberry with one of the x828 with any of the disks and works fine and reboot is ok. But when I combine the two boards the problem shows up. Seems like the problem is with Samsung disk because when i disconnect the x828 with this disk, the reboot works fine.

Anyone knows a solution?

ok. I have debugged this setup to this point. GPIO4 is the input from the x735 pertaining to the pressing and duration of the press for the power button. GPIO18 is the output from the Pi board to the x735 to power off. The problem I am seeing is with GPIO17's output. GPIO, in the script is labelled as "BOOT", but I am having an issue following the logic pertaining to the output. I can manually toggle it, and nothing happens. This is where I feel is the disconnect users are having with reboots. The shutdown script works ok, though in my configuration, I needed to ad more time to the delay. So, the question is, "What is the x735 supposed to do when GPIO17 from the RPi goes high?" Without a breakdown of the coding on the x735, it is hard to tell what the problem is.

What I recommend for a last attempt is to test only the rasp(with a sdcard) + X735. If possible. Because I'm starting to think that the X850 is not fully compatible with the X735.

Even that you have a 5v 4a power adapter connected to the X735, it's still not enough for the X850 as it is ONLY getting the energy from the usb port. What I think would help you is, make an adapter that connects from the 5v out entrance of the X735 to the micro usb in of the X850.

I purchased the x735 and x850 and the metal case. I have followed the instructions above in this Wiki exactly to install the shutdown script. When I shutdown my Pi 3 B+ the system shuts off but the board does not power down. Also when I reboot it acts the same as shutdown and does not reboot. I have to hold the momentary switch down for 8 seconds to power it off. It also behaves the same way with the internal on board momentary switch. Either the board or the script is not functioning properly. I checked and the last line in .bashrc is alias x730off='sudo x730shutdown.sh' as would be expected from the commands in the instructions above.

Hi,

So when you shutdown, how do you do it? By pressing the button for more then 3 secs or do you select shutdown in the menu? In case you are shutting it down by using Retropie, so this is the reason it is not working. But, the switch should be working. To be sure the script as installed check:

in the /etc/rc.local check if there is a line that looks like this on the bottom "/etc/x730pwr.sh &"

in the /etc/ check if there is a file called "x730pwr.sh"

and finally, check if inside /usr/local/bin/ there is a file called "x730shutdown.sh"

if some of these are missing the script was not completely installed

oh btw check if your gpio is updated with "sudo apt-get install rpi.gpio"

I checked and verified the followng: 1. /etc/rc.local the last line is "/etc/x730pwr.sh &" 2. "x730pwr.sh" exists in /etc/ 3. "x730shutdown.sh" exists in /usr/local/bin/ 4. I ran "sudo apt-get install rpi.gpio" ind it installed successfully.

If I hold the button for 4 seconds it will shut down and appear to power off successfully. However pressing the button after that when the power comes back on it does not boot up. I had to hod it down for 8 seconds first to power it off again. Then power on before it would boot up. It does not power off if I use the menu to shut down or type shutdown in the console. It also does not sucessfully reboot. The Raspberry Pi stops but doesnt reboot and I have to power off with the button and then power back on. I'm beginning to think there is a problem with my x735 board.

Let's just make some last tests

Try to remove the X850, connect the x735 to the GPIO and be sure that both of the latching switches are up(the one with the white tap and the one next to the micro usb entrance). For the power switch(the on from the metal case), try to remove it from the x735 board and try to turn it on by the blue momentary switch.

Another test with it on, is to run the command "sudo x730shutdown.sh"

Commands that are only "shutdown" or those selected by the OS interface are not going to be working to poweroff the x735...they are ONLY going to poweroff the raspberry.I have a special fix for it that I'm going to be sharing in my Youtube Channel soon.

OK so I checked both the latching switch positions and it turns out the white one was in the down position. I changed it to the up position but the behavior did not change. Using "sudo x730shutdown.sh" does work to shut down the system and power off, but same as powering down using the momentary switch, when you press the switch to turn power back on the power comes on but the Pi does not boot. I have to hold the power button down 8 second to power it off and then power it back up before it will boot. The behavior is the same if the external momentary switch is unplugged and only the internal blue momentary switch is used.

Removing the x850 was not really an option. That's where the OS is loaded from and it's only connection is via USB.

Now that the we are sure the scripts and switches are ok.

Let me ask you another thing, what is the power supply you are using?

I am making this question because when it comes to usb booting, the sdd/hdd must have enough energy to turn itself on and provide data. I'm sure it works normally without the x735 right? Now the whole unity is needing more power, as the X850 does not have a XH2.54 5v entrance, MAYBE it would work if you connected a power supply in the micro usb of the X850 and another power supply to the X735. I'm not sure if it would work, but in the wiki of the X850 it says it can be needed in circumstances with bigger ssds....I reckon it won't damage because as it does not have another 5v input connected it wouldn't get an over voltage.

The mSATA SSD is a relatively small Samsung 850 EVO 120GB MZ-M5E120BW. the power supply is a SMAKN DC 5V/4A 20W Switching Power Supply with a 5525 male jack. The system boots up fine from a cold start pressing the momentary switch. It is after a momentary switch shutdown or a software x730shutdown.sh shutdown that it will not boot up when the momentary switch is pressed. I have to do an 8 second power down for it to boot up. It is as if the switch/software shutdown does not reset a relay that allows power to get to the Pi after a soft shutdown. It behaves this way even if I unplug the power supply after the soft shutdown. I still have to power it off from the momentary switch first and then power it up again before the system will boot. I am confident this is not a power supply problem.

So to test your theory I plugged in a separate power supply I have for a Pi Zero into the 850 micro USB port. With that installed it will shut down and boot up without having to go through the process of the 8 second shutdown . It does not however explain why after the 8 second shutdown it will boot up but not immediately after a soft shutdown without the extra power supply.

Apparently if Amazon had shipped me the v3.1 of the 850 board it would have an internal 5v connector and this would not be an issue. I'd be happy to swap my v3.0 board for a v3.1 if Geekworm is amenable. I'm not happy with this board since it cannot get enough power through the USB to work as expected.

I'm glad your board is working ok tho.

I recommend you to contact GeekWorm by email, to see if they can help you out now that it's clear that the X850 is not fully compatible with the X735.

I would like to also share an idea. You can make a hole on the back of the metal case just to pass the "frankstein" cable through. So then you can connect to the micro usb and supply the X850 with 5v from the X735. This is just a workaround until you solve the problem with GeekWorm.

Here is their email: cindy@geekworm

Btw here is my channel in case you want to give some support:

I am using momentary switch and after 1-2 seconds of holding the power button it is supposed to reboot but instead it instantly shuts off. 1. not rebooting 2. because it is not rebooting and instantly turning off I suspect its a forceful shutdown.

We need function in software to power off then power on after maybe 10 seconds. Reboot not sufficient to reset some USB devices. Power off/on cycle triggered by software and HW watchdog. Must be remote, not manual press switch. Do you have product to do this?

What if I connect the x820 XH2.54 5v to the IN of the X735, and then connect the power supply to the x820. Will the safe sh work?

Hello, When istall the X735, you can power from the X735 board DC port by the power supply to X820 board by connect the 2pin cable as in the right photo of X735+X820 board.This is rigt way to power the kit. Thanks very much for your understanding! Best regards,

Hello, your method is not suggest because power supply for X820 cannot be controlled by X735 and safe shutdown won't be implemented as well. Best regards,
