The NRF24L01 module is the latest in RF modules. This module uses the 2.4GHz transceiver from Nordic Semiconductor, the NRF24L01+. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the 2.4GHz NRF24L01+PA+LNA SMA Wireless Antenna and add some extra pipelines, buffers, and an auto-retransmit feature 

Features :

1. It uses 2.4GHz global open ISM band, with license-free.
2. Transmit power is greater than +20 dBm.
3. Support six-channel data reception.
4. 2Mbit/s speed makes high-quality VoIP possible
5. Multi-frequency points: 125 frequency points meet the needs of multi-point communications and frequency hopping.
6. Low cost: integrated with high-speed signal processing parts associated with RF protocol, such as: automatically re-send lost packets and generate acknowledge signal;
7. SPI interface facilitates the communication with MCU I/O port.
8. Facilitate the development for customers, without development RF part.
9. Software programming is fully compatible with NRF24L01 modules.
