Which GND to use for sensors ? - primeroz - 06-23-2023
Hi, the only GND i see on the A2 is the one also used for POWER IN
I want to connect a PIR , i can take the `3v3` from the board but i am not sure which GND to use . Should i use the same as the `INPUT power` ?
example diagram of what i want to do
