I was able to fix the weird ADC readings with adc.atten(ADC.ATTN_11DB) # Set to 3.3V range adc.width(ADC.WIDTH_12BIT) # 12-bit resolution (0-4095, default) and I get this output now: DAC voltage: 0.25 ADC voltage: 0.18 DAC voltage: 0.5 ADC voltage: 0.41 DAC voltage: 0.75 ADC voltage: 0.63 DAC voltag...

What ESP32 should I look at for the following specs:
ESP-NOW support
ADC
DAC
GPIO
WiFi
Bluetooth optional

What dev kit should I consider?

Do I have to use C/C++ for an ESP-NOW project, or will micropython work? There are no real timing constraints for the project. All the interactions occur in what I call "human time".

I have a ESP-WROOM-32. Can I develop ESP-NOW project with that board? What board would be better for ESP-NOW development?
Thanks!

I am new to ESP32 programming. I am trying to write some micropython code, test it, edit it, test again. I can write the code, run it once, edit it, but it won't run again. I am not sure how to reset the ESP32 so the edited code runs as if it has never run before. My code: from machine import DAC, P...

I have a project prototype for a wifi controller using a Pi Zero W. The Pi Zero W is used to control a separate hardware board using the SPI bus, GPIO pins, and the I2C bus. It also provides a small web site over the WiFi connection to allow the user to interact with the hardware. The code is writte...
