Preferred PIN for ATSHA204 on Wemos D1 Mini?



  • Since I cannot find it in the ducumentation: What is the preferred pin to connect an ATSHA204 chip to a Wemos D1 mini? I see that I can set manually, but since I am doing a design from scratch anyway, why not do it properly. I guess D3 would suggest itself, since it has the pull-up already built in, while it is not connected to the LED.
