The NRF24L01+PA+LNA is a high-power, long-range 2.4GHz wireless transceiver module built around the Nordic Semiconductor nRF24L01+ chip, enhanced with an integrated Power Amplifier (PA) and Low-Noise Amplifier (LNA). The PA boosts the transmit output to +20dBm (100mW), while the LNA adds 10dB of gain on the receive path, extending the effective communication range to up to 1,000 meters in open-air line-of-sight conditions (approximately 520 meters at the 2Mbps data rate). This makes the module suitable for applications where the standard nRF24L01+ module's range of 100–150 meters is insufficient, such as outdoor telemetry, long-range remote controls, and industrial data acquisition.

The module operates in the licence-free 2.4GHz ISM band with 125 selectable frequency channels (2400–2525MHz), supporting 250kbps, 1Mbps, and 2Mbps air data rates. It includes Enhanced ShockBurst for automatic packet re-transmission and acknowledgement, 6 data pipes for star-network topologies, and three separate 32-byte TX/RX FIFOs for buffered communication. The 8-pin interface uses a 4-wire hardware SPI bus for direct connection to microcontrollers, with 5V-tolerant I/O pins for compatibility with Arduino Uno and similar 5V boards. The module is drop-in software-compatible with the standard nRF24L01+ module, so existing libraries and code can be reused without modification.

A critical design consideration is power: the module requires a 3.0–3.6V supply (3.3V recommended) and draws up to 115mA during transmission and 45mA during reception. The 3.3V regulator on many Arduino boards cannot supply this current reliably, especially during transmit bursts, so an external 3.3V regulator rated for at least 500mA and a 10µF decoupling capacitor close to the module's VCC/GND pins are strongly recommended to prevent unstable operation or communication dropouts. The module measures approximately 41mm × 15.5mm and is supplied with an external 2dBi SMA antenna (reverse-polarity SMA connector).
