AIY and Pi4j (Voice V1) GPIO Reference
I’m trying to use a Google AIY Voice V1 with Pi4J. I had a bit of trouble finding the pins, so I’m posting this here in case anyone else is looking.
Basically; there are three numbers for the pins. The AIY SDK uses one number, the header has a different number, and (after experimentation I’ve determined that) the Pi4J API uses a different layout.
Anyway, this table shows the RaspiPin
for the Button and LED interfaces.
Action | pi4j GPIO | J6 Diagram | AIY SDK PIN Name |
---|---|---|---|
LED | RaspiPin.GPIO_06 | 22 | 25 |
Button Press | RaspiPin.GPIO_04 | 16 | 23 |
