This module is based on Nordic Semiconductor's NRF24L01+ transceiver IC operating in the 2.4 GHz band, but adds PA (power amplifier) and LNA (low-noise amplifier) circuits and a reverse-polarised SMA connector for maximum RF range. It ships with a 2.4 GHz, 2 dB antenna, and at 250 kbps in open air it can reach an 800 to 1000 m communication distance.
Because the RF front end is more capable than a basic NRF24L01, this variant is the one to choose when a plain module's range is not enough for your project.
The 2.4 GHz band is global and license-free. Transmit power is greater than +20 dBm, the module supports six-channel data reception and a 2 Mbit/s speed, and 125 frequency points support multi-point communication. It uses an SPI interface for communication with a microcontroller's I/O port, and software is fully compatible with standard NRF24L01 modules.
Power the module from a clean, adequately rated supply, since radio and camera modules draw current in short bursts that a weak supply cannot follow. Keep the antenna clear of metal and ground planes, and start with the maker's example code before writing your own.
Makers who have outgrown a basic NRF24L01's range and need a long-distance link for remote sensors, telemetry or outdoor controls.
Handle the SMA connector gently when swapping antennas, since repeated over-tightening can strip the threads on a small module. Keep the antenna vertical and away from large metal panels for the most consistent range, and avoid coiling the antenna cable tightly, which can reduce its efficiency.
