NRF24L01 Wireless Module 2.4GHz Radio Transceiver Module

The NRF24L01 is a single chip transceiver module designed to operate in the 2.4-2.5GHz worldwide ISM band. 

Has a range of up to 100 meters. The transceiver supports six channels of data reception.

Low operating voltage of 1.9-3.6V and a high data rate of 2Mbps

 

It is ultra-compact, with a built-in 2.4GHz antenna and a compact size of 15 x 29mm

The NRF24L01 has low power consumption of 14mA. It integrates all RF protocol high-speed signal processing, such as automatically resending lost packets and automatically generating an acknowledge signal. 

The SPI interface can take advantage of the microcontroller SPI port or microcontroller I/O port to simulate the internal FIFO, making it easy to use with a variety of low-speed microprocessor interfaces and low-cost microcontrollers.

It has an automatic retransmission function, automatic detection and retransmission of lost packets, and software-controlled retransmission time and number of retransmissions.

The module automatically sends a reply after receiving a valid data packet. It has fixed frequency detection signals without any additional programming and carrier detect.

It also has built-in hardware CRC error detection and point-to-multipoint communication address control. The packet transmission error counter and carrier detection can be used for frequency hopping set. 

It can also set up six receiving channel addresses with a choice of open receive channels. The standard pin Dip2.54MM spacing interfaces make it suitable for embedded applications.
