Howto use Mega 2560 + ESP8266 board


i would like to use this board:

i already use this board before with code on the Mega and AT Firmware on the esp.

now i flashed esphome to the ESP and i set the switches back

what would i need to get the communication going?

Well you can program the ESP part with ESPHome but it’ll give you only access at peripherals connected straight at ESP ! For rest you’ll still need to put a program in the Mega chipset and get it to communicate with the ESP :wink:
Unhappy there are no schematics of board on your link all in german :frowning:

Hi, thanks for your answer. I found some more documents:
