The NRF24L01 is a monolithic transceiver chip that operates in the world's common ISM band of 2.4-2.5GHz. The wireless transceivers include: frequency generators, enhanced "SchockBurst" mode controllers, power amplifiers, crystal oscillators, modulators and demodulators device.

Output power channel selection and protocol settings can be set via the SPI interface. Almost can be connected to a variety of microcontroller chips, and complete the wireless data transmission work. Very low current consumption: When operating in transmit mode, the current consumption is 0dBm, the current consumption is 11.3mA. Working in the receiving mode, the current consumption is 12.3mA.If work in power down mode and standby mode,clower current consumption.

• Low operating voltage: 1.9 ~ 3.6V low voltage operation
• High rate: 2Mbps, because the air transmission time is very short, greatly reducing the collision in the wireless transmission (set air transfer rate is 1Mbps or 2Mbps)
• Multi-frequency: 125 frequency points to meet the needs of multi-point communication and frequency hopping communication
• Ultra-small: built-in 2.4GHz antenna, small size, 15x29mm (including the antenna)
• Low power consumption: When working in answer mode communication, fast air transmission and start time, greatly reducing the current consumption.
• Low application cost:NRF24L01 integrates all the high-speed signal processing part related to RF protocol.
• Easy to develop: As the link layer is fully integrated on the module, very easy to develop
