Re: ESP32-S3-MINI-1U - safe GPIO choices?
This one told me something different: https://www.revk.uk/2023/08/esp32-s3-mini-1-gpio.html I suppose it's very important to know exactly what version of ESP32 we're working with.. This one says be careful with GPIO0 (boot mode),19 and 20 (USB data) and also 26,43,44,46 (3 and 45) And then I'll try ...

Re: ESP32-S3-MINI-1U - safe GPIO choices?
Thank you! Okay I'll stay away from GPIO 6 - 11 I guess I could use GPIO 2-5 for the analog inputs then. The only reason only used even inputs was that on my Arduino Nano ESP32, I had trouble reading two analog inputs next to each other. I skipped one and it worked. Then you mention the auto-reset c...

ESP32-S3-MINI-1U - safe GPIO choices?
Okay this is my first try in making a custom board with ESP32. (Or any IC for that matter) I'm using the S3-MINI-1U and I'm a little unsure about which GPIOs are best to use and which need to be left alone. Also I'm unsure if I missed something cruzial to make it work correctly? Here my first setup ...
