Does anyone know if a small board like this one (http://digistump.com/products/1) (with or w/o USB) exists with Bluetooth chip (not WiFi)?
I'm looking for a microprocessor with BT that I can program with Arduino or Micropython.
Micropython on a processor with 512 bytes of RAM?
esp8622 can run with micropython but it has wifi, not BT. Esp32 has wifi and BT but too an over kill for my project. Ok, so, without micropython, just with simple arduino code.
The nRF52840 is probably overkill but it has BLE (not classic BT). Adafruit and SparkFun ship boards using this chip. Arduino announced two Nano 33 BLE boards using this chip. Adafruit supports Arduino and CircuitPython. Not sure about Micropython.
