Upgraded NRF24L01 Module

Upgraded NRF24L01 Module

$8.00

NRF24L01 2.4GHz Wireless Transceiver Module with PA/LNA & SMA Antenna

High-performance NRF24L01+ transceiver module featuring a built-in power amplifier (PA) and low-noise amplifier (LNA), paired with a removable high-gain SMA antenna. Designed to deliver an enhanced link budget and extended line-of-sight range compared to standard NRF24L01 modules, making it suitable for long-range wireless communication in embedded and IoT projects.


Key Features

  • Enhanced Range: Integrated PA & LNA improve signal strength and reception sensitivity

  • Removable SMA Antenna: Flexible positioning and easy antenna upgrades

  • SPI Interface: Compatible with Arduino, Raspberry Pi, ESP32, STM32, and similar platforms

  • Compact Design: Easy to mount and integrate into sensor networks


What’s Included

  • 1 × NRF24L01 2.4GHz Transceiver Module

Typical Applications

  • Long-range wireless sensor networks (Arduino, Raspberry Pi)

  • Telemetry systems for weather stations and remote monitoring

  • Wireless control for robotics and RC projects

  • Home automation networks and repeater nodes

  • Point-to-point or mesh IoT communication (with appropriate protocol)


Wiring & Setup

Important: This module operates at 3.3V logic. Do not connect directly to 5V systems.

Connections:

  • VCC → 3.3V regulated supply

  • GND → Ground

  • CE → Any configurable digital pin

  • CSN / CS → SPI chip-select pin

  • SCK → SPI clock

  • MOSI → SPI data (MCU to module)

  • MISO → SPI data (module to MCU)

  • IRQ → Optional interrupt pin

For 5V microcontrollers (e.g., Arduino UNO, Mega), use a 3.3V regulator (such as AMS1117-3.3) and level shifters on SPI lines.


Installation Notes

  • Use a stable 3.3V power source

  • Position the SMA antenna vertically and in open air for optimal range

  • Avoid enclosing the antenna in metal housings to maintain signal quality
