2.4G RF module - nRF24L01

GENERAL DESCRIPTION
nRF24L01  is  a  single  chip  radio  transceiver  for  the world wide 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 and Enhanced ShockBurst™ protocol  engine.  Output  power,  frequency  channels,  and  protocol  setup  are  easily programmable through a SPI interface. Current consumption is very low, only 9.0mA at  an  output  power  of  -6dBm  and  12.3mA  in RX mode. Built-in Power Down  and Standby modes makes power saving easily realizable.
