NRF24L01+PA+LNA SMA 2.4GHz Wireless Transceiver Module
Package QFN-20
NRF24L01+PA+LNA SMA 2.4GHz Wireless Transceiver Module overview
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 is PA and LNA circuit on board, with the external antenna it can reach a long distance than the one without these parts.
This module comes with the 2.4G antenna (2DB), with a 250Kbps transmission rate in the open air it can reach 800-1K meters communication distance.
