NRF24L01 is a single chip radio transceiver for the 2.4 - 2.5 GHz ISM band. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator. Programmable through a SPI interface. Current consumption is, only 9.0mA at an output power of -6dBm and 12.3mA in RX mode.
 
Maximum operating speeds up to 2Mbps.
Low-power 1.9 ~ 3.6V, only 1uA on Power down mode.
Built-in 2.4Ghz antenna.
Notice: Transceivers integrated module , transmit or receive can not be simultaneously by one module.
