NRF24L01 is a module that works in the 2.4-2.5GHz worldwide ISM band. It’s a single-chip transceiver, wireless transceiver, including the frequency generator, the enhanced SchockBurstTM mode controller, power amplifier, crystal amplifier, modulator – demodulator. Output channel selection and protocol set by the SPI interface. Additionally, it has very low current consumption, lower current consumption mode 12.3mA, power-down mode and standby mode. When in transmit mode emission power 6dBm, current consumption is 9.0mA. Note that it can transmit and receive over 100 meters in open air! Support six channels of data reception. 2.4Ghz lisence-free ISM band Highest data speed 2Mbps，high efficient GFSK modulation, anti-interfere, specially suit for indutrial control 125 channel, can reach different point or jump frequency communication needs Integrated hardware 8/16 bytes CRC confirmation and point to mutiple points communication adress control, combine TDMA – CMDA – FDMA working principle, enable wireless communication. Low power comunpiton 1.9 – 3.6V ，Standby mode only need 1uA ； Module can set address by software, only output data when receive own device address(display interruption), can directly connect to any single chip, easy to program. Send and receive interruption signal, send 28 bytes maximally each time. Integrated special voltage regulator, use any kind of power including DC/DC power can have better communication effort. Standard DIP jack, easy for embedded system application. CLK，DATA，DR three wires connection，easy to program。 Two channels data receive, embedded circular antennas, communication distance is 20-30 meters in open and no interferes environment. Dimensions: 34x17x1mm（PCB embedded antennas)
