This module uses the newest 2.4GHz transceiver from Nordic Semiconductor, the nRF24L01.This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature. Now we make a breakout for nRF24L01 , and build the smallest system for it , also the wireless circuit . You can use it in you project without any wireless design , just need to leave a 8 pins interface to this module , use the SPI interface to control the module on transferring data. Features Worldwide license-free 2.4GHz ISM band operation 250kbps, 1Mbps and 2Mbps on-air data-rate options Enhanced ShockBurst?hardware protocol accelerator Ultra low power consumption?months to years of battery lifetime Specification Power supply : 1.9~3.6V IO port working voltage : 0~3.3v / 5v Transmitting rate : +7dB Receiving sensitivity : -90dB Transmission range : 250m in open area Dimension : 15x29mm Wiki & External links nRF24L01+ datasheet Adruino Playground - nRF24L01 nRF24L01 Module Demo Fro Arduino Wiki link
