A long-range 2.4 GHz wireless transceiver module based on the NRF24L01+ chip with an integrated power amplifier (PA) and low-noise amplifier (LNA). The added PA and LNA significantly extend the effective communication range up to 1100 metres in open-air line-of-sight conditions. Connects via SPI to Arduino or any other microcontroller.

The module operates in the licence-free 2.4 GHz ISM band with 125 selectable frequency channels, supporting point-to-point and star network topologies. Software-compatible with standard NRF24L01 modules.
