Hello, I bought an arduino atMEGA 2560 WIFI based card, you know that the switches are sent as not set, I passed the ESP module, I can't even assign a code from the USB. At the beginning, this makes me nervous. man, what's wrong with this card, please help
nothing is wrong with it, but it is complex. you need to understand the pieces.
it is a very good board to create large sketches with many inputs and outputs and wifi.
