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.
