nRF24L01+ brings wireless communication running on license-free 2.4 GHz ISM band. As an added value, this transceiver module has Power Amplifier (PA) and Low Noise Amplifier (LNA) circuit on board with external antenna for more stable performance and to boost communication range up to 1000m in ideal condition.
The board is compact and can be easily embedded in any project. It has SPI connection for interfacing with microcontrollers/microcomputers. So you could use this module to connect two or more Arduinos or Raspberry Pi wirelessly.
The recommended operating voltage to be connected to the VCC pin of this module is 3.3V and you cannot run it with more than 3.6V. Else, you will risk damaging the board. Good thing is, the other pins are 5V tolerant.
