NRF24L01 Wireless Module Transceiver 2.4 GHz + SMA Antenna +  Breakout Adapter On-Board 3.3V Regulator - Arduino
【NRF24L01】is 2.4GHz ISM band transceiver for arduino, which has the abilities of auto-acknowledge and auto-retransmit and support up to six channels of data reception.
【NRF24L01】Includes on board support components and the RFX2401C which is the PA (Power Amplifier) and LNA (Low-Noise Amplifier)
【NRF24L01】The module has 5V tolerant inputs which allows for direct connection of SPI pins to the Arduino.
【Wireless Module】Small power on SMD LED indicator; On-board 3.3V voltage regulator accepts your Arduino +5V supply and provides 3.3V for the attached "NRF24L01+" module.
