Hi Rui
In your manual you say that you can use ESP32/8266 flashed in MicroPython, in the Arduino IDE, but first upload a code. Where do you find this code.
Thanks

Hello Neil, here’s what I mean:

• After uploading any Arduino code to your ESP32/ESP8266 board, the MicroPython firmware will be automatically erased. So, to use any Arduino sketch simply upload it and it will work.
• If you want to go back to MicroPython, you need to re-flash the ESP boards with MicroPython firmware.

I hope this answers your question. Regards,
Rui
