All the experiments in this kit are done with SunFounder Uno R3 board, but they are also compatible with SunFounder Mega 2560, SunFounder Nano and all official Arduino Boards. All the code included in this kit works with these boards.
So what does COMPATIBLE mean here? It means you can use any of the three boards to do the same experiment with the same wiring. Take turning on an LED as an example. We use SunFounder Uno as the microcontroller, but you can also use SunFounder Nano or SunFounder Mega 2560 to serve the same function. Just select the right Board and COM when compiling.
