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 Specifications Parameter Details Chip nRF24L01+ (with PA / LNA) Frequency 2.4 GHz ISM Band Interface SPI (MOSI, MISO, SCK, CSN, CE) Antenna Removable SMA (included) Operating Voltage 3.3V (logic) — Do not use 5V Range Enhanced vs standard modules; depends on antenna, environment, and LOS Mounting PCB module with pin header Condition New Item Specifics Brand: Unbranded / Generic Model: NRF24L01+ PA LNA SMA MPN: Does Not Apply Type: 2.4GHz Transceiver Module Frequency: 2.4 GHz Interface: SPI Antenna: SMA removable (included) Operating Voltage: 3.3V (logic) Country/Region of Manufacture: China Custom Bundle: No 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
