Revision as of 12:01, 25 July 2020
1. Power Jack and Connectors
Power input | 5Vdc +/- 5% , ≥3A |
DC Power Plug Size | 5.5*2.5mm |
USB power in socket | Type-C |
UPS power output | 5.1Vdc 8A |
Power output connector | XH2.54mm 2pin |
- X708 powers the Raspberry Pi via the 40-pin header (Pin 2 & 4)
- Don't power the Raspberry Pi via the Pi's type-C USB socket
- X708 can be powered via the onboard DC jack or Type-C USB power socket
2. 6-Pin Function Header
Jumper Name | Usage |
---|---|
PLD
(Power loss detection) Pin 1&2 |
|
AON
(Auto power-on) Pin 3&4 |
|
ASD
(Auto shutdown) Pin 5&6 |
1. Battery voltage must be >3Vdc 2. Insert the battery into the holder 3. Wait 3 seconds then insert the jumper 4. If the jumper inserted before battery, remove battery & jumper then repeat step 1, 2 and 3.
|
