GERUI Pack of 4 NRF24L01 + PA LNA Wireless Transceiver Module, 2.4G 1100 m RF Radio Can Be Applied Point to or Form a Star Net, with SMA Antenna Compatible for Arduino

NRF24L01 Wireless Transceiver:NRF24L01 is a single-chip wireless transceiver for the worldwide ISM band from 2.4 to 2.5 GHz. Compatible with Arduino and Raspberry Pi Avoid errors: Avoid R&D costs and shorten development time by using the NRF24L01+PA+LNA module instead of developing the RF part yourself. The NRF24L01+PA+LNA module has 5V tolerant inputs that allow direct connection of SPI pins to the Arduino. Optimised transmission functions: optimise transmission efficiency and minimise interference with the NRF24L01 module, which ensures optimal tuning and low harmonics. Range: 800+ metres of line of sight. A professional bidirectional RF power amplifier consists of RF switches, bandpass filters etc., which significantly extends the effective communication distance. Easy to use: automatic confirmation and automatic retransmission. Customers only need to add an MCU to control NRF24L01P + PA + LNA via the SPI port and wireless module to complete the design of a wireless data transmission system with extremely long range, significantly reduces research and development costs and shortens the research and development cycle. Widely used: NRF24L01 module for monitoring wireless peripherals, remote control systems such as RC vehicles and remote control electronics, wireless voice transmission such as VoIP, wireless sensor networks, wireless networks, home and business automation
