A quality Mega 2560-compatible board from ELEGOO for builders who want the Mega’s big pin count without the genuine-board price. It is the same ATmega2560 pinout and runs identically in the Arduino IDE, so all the same arm code and libraries apply. A pragmatic choice if you are buying several boards for a class or expect to make the occasional wiring mistake.
