NRF24L01 is a work in the single chip transceiver chip 2.4-2.5GHz universal ISM band wireless transceiver, including: frequency generator enhanced controller in SchockBurstTM mode power amplifier amplifier modulator demodulator output channel selection and protocol settings can be set consumes very low current through the SPI interface, when operating in the transmit mode transmitting power 6dBm when the current consumption is 9.0mA acceptance model for the current 12.3mA power down mode and the standby mode, consumption mode is lower.

Open ISM frequency band, the maximum 0dBm transmitter power, free license to use.
Support six channels data reception

1 Low working voltage: 1.9 ~ 3.6V

2 High speed: 2Mbps, due to the transmission time is very short, greatly reducing the collision phenomenon in the wireless transmission (air transmission rate software set 1Mbps or 2Mbps)

3 Multi frequency: 125 frequency points, meet the multipoint communication and frequency hopping communication needs

4 Tiny: built-in 2.4GHz antenna, small volume, 15x29mm (including antenna)

5 Low power: when working in answer mode communication, air transport and starting time of fast, greatly reducing current consumption.

6 Low cost: NRF24L01 integrates all the relevant RF agreements and high-speed signal processing, such as: automatic retransmission of lost packets and automatically generate a response signal, SPI interface, NRF24L01 can use the hardware SPI port connection or by SCM I/O port simulation, internal FIFO and all kinds of high and low speed microprocessor interface, easy to use low cost microcontroller.

7 Facilitate development: due to link layer is fully integrated in the module, very easy to develop. Automatic retransmission, automatic detection and retransmission of lost packets, retransmission time and the number of retransmissions can control software of automatic storage did not receive a response signal packet automatic answering function, upon receipt of a valid data, module automatically transmits a response signal, without further programming carrier wave detection - fixed frequency detection built-in hardware CRC error detection and point to multipoint communication address control data packet transmission error counter and carrier detection function can be used for frequency hopping settings can be set at the same time six receiving channel address, can selectively open channel standard pin spacing of Dip2.54MM interface, convenient for embedded applications
