NRF Antenna with SMA to UFL Connector

NRF24L01+ PA + LNA 2.4GHz Wireless Transceiver Module with SMA Antenna

The NRF24L01+ PA+LNA Wireless Transceiver Module is a long-range 2.4GHz RF communication module designed for reliable and low-cost wireless applications. Operating in the global license-free ISM band, it features a built-in Power Amplifier (PA) and Low Noise Amplifier (LNA) for extended communication distance.

With a reverse-polarized SMA connector and 2dBi external antenna, the module can achieve up to 1000 meters range in open area (no obstacles) depending on data rate.

It communicates via SPI interface, making it easy to integrate with microcontrollers such as Arduino, ARM, PIC, AVR, STM32, and other MCU platforms. The module supports auto-retransmission, acknowledgment, and multi-channel communication for stable wireless performance.
