nrf24l01芯片资料英文 文档

nRF24L01 is a single chip radio transceiver for the world wide 2.4 - 2.5 GHz ISMband. The transceiver consists of a fully integrated frequency synthesizer, a poweramplifier, a crystal oscillator, a demodulator, modulator and Enhanced ShockBurst™protocol engine. Output power, frequency channels, and protocol setup are easilyprogrammable through a SPI interface. Current consumption is very low, only 9.0mAat an output power of -6dBm and 12.3mA in RX mode. Built-in Power Down andStandby modes makes power saving easily realizable.
