NRF24L01+PA+LNA Wireless Transceiver Module (1000m Range)

NRF24L01+PA+LNA Wireless Transceiver Module – Long Range 2.4GHz Connectivity

Overview

The NRF24L01+PA+LNA module is a compact 2.4GHz wireless transceiver designed for reliable, low-power data transfer in Arduino, Raspberry Pi, and other microcontroller projects. This enhanced PA and LNA version boosts transmit and receive sensitivity to extend range up to 1000m in open space when paired with a suitable external antenna.

Key Features

• NRF24L01 RF transceiver core operating at 2.4GHz
• Power amplifier (PA) and low-noise amplifier (LNA) for extended range
• Up to 1000m open-space range with a quality antenna
• Low power consumption, suitable for battery-powered IoT devices
• SPI interface for simple communication with microcontrollers
• Compact PCB module with standard pinout for easy wiring

Technical Specifications

• Chipset: Nordic Semiconductor nRF24L01+
• Frequency: 2.4GHz ISM band
• Range: Up to 1000m in open space (antenna and environment dependent)
• Interfaces: SPI (MOSI, MISO, SCK), CE, CSN, IRQ
• Supply voltage: 3.3V (do not apply 5V directly to module pins)
• Current consumption: Low-power modes supported; transmit current higher due to PA
• Antenna: External antenna connector or onboard antenna depending on model

Compatibility and Integration

• Works with Arduino, Raspberry Pi, ESP8266/ESP32 and other 3.3V microcontrollers
• Supported by popular libraries such as RF24 for Arduino and compatible drivers for Raspberry Pi
• SPI-based configuration makes integration straightforward for beginners and pros

Wiring and Setup Tips

• Power the module with a stable 3.3V supply – use a regulator if powering from 5V
• Connect MOSI, MISO, SCK, CSN, CE, and IRQ pins according to your board’s SPI pins
• Add decoupling capacitors near the supply pins to prevent voltage dips during transmit peaks
• Use level shifters or ensure 3.3V logic compatibility to avoid damaging the module

Range and Performance Notes

Range depends on antenna quality, environmental interference, and antenna placement. The PA+LNA variant increases transmit power and receiver sensitivity to provide long-range links, but real-world distances will vary indoors and in crowded RF environments. Optimal performance is achieved with a clear line-of-sight and an appropriate external antenna.

Tips to Maximize Range

• Use a high-gain external antenna and position it vertically for best polarization match
• Place modules away from large metal objects and sources of electromagnetic interference
• Lower data rate settings can improve range and link reliability
• Power the PA with a stable 3.3V supply capable of delivering peak current

Common Use Cases

• Wireless sensor networks and remote telemetry for IoT
• RC control and robotics for untethered operation across rooms or yards
• Home automation and smart switches with reliable RF links
• DIY RF transceiver projects and educational prototypes

Libraries, Resources and Examples

• Arduino RF24 library – quick start examples and multi-node setups
• Raspberry Pi drivers with wiring and SPI configuration guides
• Community tutorials for mesh networking and low-power modes

Safety and Handling

• Do not apply 5V directly to the module pins – use a 3.3V supply or regulator
• Avoid static discharge – handle the board by its edges and ground yourself before touching
