Pin definition
Usage
First of all, you need two Arduino boards and at least two RF modules, one to transmit and the other to receive. If you don’t have, you can get them in our store in a very low cost. (Order nRF24L01 module)If you use a standard Arduino board, you should use the Arduino board’s 3.3V pin to provide power. Beacuse the nRF24L01 module is worked at 1.9-3.6V voltage level.
