NRF24L01+PA+LNA 5V Relays Temperature Control SystemsNRF24L01+PA+LNA SMA Wireless Transceiver Antenna The NRF24L01 module is a state of the art RF module that uses Nordic Semiconductor's 2. 4GHz transceiver, the NRF24L01+. This IC operates in the 2. 4GHz band and comes with many new features, such as additional pipelines, buffers, and an auto retransmit function. The board has a reverse polarized SMA connector that maximizes the RF range, as well as a PA and LNA circuit, which enables long distance
