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

Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- IRQ
- IRQ (interrupt request) is a signal line a device uses to alert a microcontroller that something needs attention, so the microcontroller does not have to poll continuously. Wiring an IRQ pin to a free input lets code respond promptly to events such as new data being ready.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- RX
- RX means receive, usually showing data being received by the board. An RX indicator LED can help with troubleshooting USB or serial communication.
- 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.
- TX
- TX means transmit, usually showing data being sent from the board. A TX indicator LED can help you see when the board is communicating or uploading code.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
