NRF24L01+ 2.4GHz Wireless Transceiver Module — PA+LNA, Up to 1000m Range, SPI
The NRF24L01+ with PA+LNA is a long-range 2.4GHz wireless transceiver module based on Nordic Semiconductor's nRF24L01+ IC, enhanced with an external power amplifier (PA) and low-noise amplifier (LNA) for dramatically extended range compared to the standard NRF24L01 module. With up to 1000m line-of-sight range, 2Mbps data rate, and 125 selectable channels, it is the preferred choice for Arduino long-range wireless sensor networks, remote control systems, and multi-node IoT applications.
