Generic 2A16 NRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module with SMA Antenna 2.4G 1100m Compatible with Arduino

Ultra-long-distance data transmission, high-power, high sensitivity, integrated PA and LNA, optimized for minimal RF interference, compact design, Arduino compatible

VCC supplies power to the module (1.9V to 3.9V); connecting to a 5V pin will likely damage the module. Connect VCC to Arduino's 3.3V output and GND to ground. CE and CSN pins can be connected to any digital pin (e.g., #8 and #9). SPI pins (SCK, MISO, MOSI) must be connected to specific Arduino SPI pins (e.g., Digital 13, 12, 11 for UNO/Nano V3.0); check official documentation for other Arduino boards. Two circuits are needed, one for transmitter and one for receiver, with identical wiring. Install the RF24 library (by TmRh20) via Arduino Library Manager. Messages can be up to 32 bytes in length. Ensure both transmitter and receiver use the same 5-character pipe address.
