Hey guys can you help me this esp8266 relay module not working my pc cant see this board in ports arduino the cable supports data
What does this have to do with the Arduino Leonardo board?
Have a read of the "How to get the best out of this forum" pinned at the top of this section.
Where did you get this board from?
What does the documentation for the board say?
Do you need to ground a pin in order to activate a bootloader maybe?
I don't see anything that looks like a USB-Serial chip - perhaps it's underneath the board?
Or maybe that USB connector is there to just supply power to the board?
