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.
Key Features
- Extended Range – Up to 1100 m with PA (+20 dBm) and LNA (+10 dB gain)
- 2.4 GHz ISM Band – Licence-free, 125 frequency channels
- High Data Rate – Up to 2 Mbit/s
- 6-Channel Receive – Simultaneous multi-pipe data reception
- Auto Retransmit – Built-in packet loss recovery and acknowledgement
- SPI Interface – 8-pin connection to any microcontroller
- NRF24L01 Compatible – Drop-in software replacement for standard modules

Jargon buster
Plain-language definitions for the technical terms used above.
- IRQ
- Short for interrupt request, a signal pin a device uses to get a microcontroller’s attention when something needs handling. It matters here because I2C communication with the sensor requires connecting the IRQ pin to a suitable input pin.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
