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 in some extra pipelines,
buffers, and an auto-retransmit feature, and you have the nRF24L01+!
This board features a reverse polarized SMA connector for maximum RF
range. And there is the PA and LNA circuit on board, when used with the
external antenna, it can reach longer distances 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.
Note: We now populate these boards with the nRF24L01+. The '+' version
of the IC has improved range, sensitivity, and data rates. The command set
is backward compatible with the original nRF24L01.
