The module includes an onboard power amplifier (PA) and a low-noise amplifier (LNA) that help to boost the signal strength and improve the module’s sensitivity, thereby extending its range. The PA module provides up to 20 dBm of output power, while the LNA module offers a gain of up to 10 dB. This makes the nRF24L01+PA+LNA capable of transmitting data over long distances, even in environments with background noise.

The NRF24L01+PA+LNA module supports data rates up to 2Mbps and has a maximum range of up to 1100 meters in open space with line-of-sight.

It is recommended to pair this module with the NRF24L01 Wireless Transceiver Socket Adapter Board for ease of powering and wiring.
