NRF24L01 is a universal ISM band monolithic transceiver chip works in the 2.4-2.5GHz
Wireless transceiver including: Frequency generator, enhanced type, SchockBurstTM, mode controller, power amplifier, crystal amplifier, modulator, demodulator
The output power channel selection and protocol settings can be set extremely low current consumption, through the SPI interface
As the transmit mode, the transmit power is 6dBm, the current is 9.0mA, the accepted mode current is 12.3mA, the current consumption of the power-down mode and standby mode are lower
Built-in 2.4GHz antenna, supports up to six channels of data reception
Size: 15 x 29mm
Low operating voltage: 1.9-3.6V
125 channels, multi-point communication and frequency hopping to meet the communication needs
High Rate: 2Mbps, as air transmission time is very short, greatly reducing collision phenomena in wireless transmission (air transfer rate of software setting: 1Mbps or 2Mbps)
Low power consumption: When the answer mode communication, fast air transmission and start-up time, which greatly reduces the current consumption
Low application cost: NRF24L01 integrated part of all high-speed signal processing related to RF protocol, such as: automatic retransmission of lost packets and automatically generate response signals, etc.
NRF24L01 SPI interface: hardware SPI port, MCU I/O ports
Internal FIFO compatible with a variety of microprocessor interface, micro-controller is convenient
