2.4GHz NRF24L01 PA LNA SMA Antenna Wireless Transceiver Communication Module 1km
The NRF24L01 module is the latest in RF modules. This module uses the 2.4GHz transceiver from Nordic Semiconductor, the NRF24L01 . This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature – very nice!
This board features a reverse polarized SMA connector for maximum RF range. And there are PA and LNA circuit on board, with the external antenna it can reach long distance than the one without these parts.
This module comes with the 2.4G antenna (2DB), with 250Kbps transmission rate on open air it can reach the 800-1K meters communication distance.
