NRF24L01 monolithic transceiver chip in the 2.4-2.5GHz universal ISM band, the wireless transceiver is a work comprising: a frequency generator enhancement type SchockBurstTM mode controller power amplifier crystal amplifier modulator demodulator output power of the channel selection and protocolthrough the SPI interface settings can be set very low current consumption,when working in the transmit mode the transmit power 6dBm current consumption is 9.0mAaccepted mode for lower current consumption mode 12.3mA power-down mode and standbymode.
1 low working voltage: 1.9 ~ 3.6V low voltage operation
High rate: 2Mbps air transmission time is very short, and greatly reduce the phenomenon of collisions in wireless transmission(software setting air transfer rate of 1Mbps or 2Mbps)
3. Frequency: 125 frequency points to meet the communication needs of multi-point communication and frequency hopping
Ultra-small: 2.4GHz built-in antenna, compact, 15x29mm (including antenna)
5 Low power consumption: when work in answer mode communication, fast air transmission and start-up time, which greatly reduces the current consumption.
Low application costs: NRF24L01 integrated part of all high-speed signal processing related to RF protocol, such as: automaticretransmission of lost packets and automatically generate response signals, etc. NRF24L01 SPI interface can usemicrocontroller hardware SPI port or MCU analog I / O port, internal FIFO with a variety of high and low speed microprocessor interface, easy-to-use low-cost microcontroller.
7 to facilitate the development: the link layer is completely integrated in the module, and is very easy to develop. Automatic retransmission function, automatic detection and retransmission of lost packets and retransmission time and the number of retransmissions can be software-controlled automatic storage did not receive the response signal packet automatic answerfunction, valid data is received, the module automatically sends a reply signal, without prior programming carrier Detect – fixedfrequency detector built-in hardware CRC error detection and point-to-multipoint communication address control packettransmission error counters and carrier detection function can be used to hopping six settings can be set at the same timereceive channel address, can be selectively the nature open the the receive channel standard pin Dip2.54MM spacing interfaceeasy embedded applications.
