Raspberry Pi DIDO Board
The DIDO is upgraded to Version 1.3, and it's support the raspberry pi 4 model B now. We have only reduced the PCB size, nothing else has changed.
How to use the DIDO on Raspberry PI 4B Please refer to File:How to use the DIDO on Raspberry PI 4B-EN.pdf
DIDO module includes components like relays,switches, gigital and analog I/O that will allow for connection to sensors ,motors, lights, etc. and be controlled by the Raspberry Pi board.
The digital DIDO module interface board fits the original Raspberry Pi models A and B. DIDO module has been redesigned to fit the Raspberry Pi models A and B.

- Ensure that no power is supplied to Raspberry Pi, or DIDO boards
when plugging or unplugging. DIDO sits neatly above the Raspberry Pi and connects using the expansion connector. Take care to ensure all expansion pins are lined up with the holes on the DIDO socket. Check the alignment for left and right, and front and back before pushing down and never force the boards together if they don’t slide smoothly.
