NRF24L01+ 2.4GHz Wireless Transceiver Module

The NRF24L01+ is a compact 2.4GHz wireless transceiver module designed for short-range communication between microcontrollers. It uses the SPI interface to connect with development boards such as Arduino, ESP32, STM32, and Raspberry Pi. The module supports data rates of 250kbps, 1Mbps, and 2Mbps, with 125 selectable RF channels for flexible wireless communication. Operating at 1.9V–3.6V, it is suitable for low-power embedded applications. Its built-in PCB antenna makes it compact and easy to integrate into robotics, wireless sensor networks, remote-control systems, and IoT projects. The typical open-area communication range can reach approximately 100 meters, depending on antenna placement, interference, power supply, and environment. Use a stable 3.3V supply; do not connect it directly to 5V power.
