This is a long distance 2.4G wireless module which basic on nRF24L01+ chip, and there is the PA and LNA circuit on board, with the external antenna it can reach long distance than the one without these parts. It's the same interface as the nRF24L01+ wireless module , so you use thie module to replace it in your project to ger long transmission distance without any change.
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.
