What it is
The ShillehTek NRF24L01+ PA LNA Wireless Transceiver Module Antenna 1100m Range is a 2.4 GHz NRF24L01+ radio module with an onboard PA+LNA stage and a shielded RF section to help maintain steadier links in noisy environments. It includes a detachable SMA 2.4 GHz antenna, making it a practical long-range upgrade for Arduino, Raspberry Pi, sensors, telemetry, and outdoor IoT projects.
Pins
Pin names and order can vary by board revision. Refer to the silkscreen labels on the module and the listing photos for the exact pinout, then match those labels to your NRF24L01+ library wiring guide (Arduino/Raspberry Pi SPI connections).

Frequently Asked Questions
How do I wire the NRF24L01+ PA+LNA module to an Arduino or Raspberry Pi?
Use your platform’s SPI wiring guide for NRF24L01+ modules and match each connection to the module’s silkscreen pin labels. Because pin order can vary by revision, verify against the listing photos before powering up.
Is this a drop-in replacement for a standard NRF24L01+ module?
Yes—it's designed to be compatible with standard NRF24L01+ libraries, so most sketches and examples work with the same radio configuration. Always confirm wiring and physical pin order first.
What does PA + LNA mean on the NRF24L01+ long-range module?
PA (Power Amplifier) helps boost transmit output and LNA (Low Noise Amplifier) improves receiver sensitivity. Together they can help extend practical range compared with typical small onboard-antenna boards.
Can I replace the included antenna with a higher-gain SMA antenna?
The module uses a standard SMA connector and ships with a detachable 2.4 GHz antenna, so swapping to another compatible 2.4 GHz SMA antenna is straightforward. Range and reliability will still depend on environment and antenna placement.
