The JRF-P21/17/13TRX series modules adopt the high-performance WIRELESS transceiver chip of the United States, which is a complete, coin-sized, low-power wireless  

Transceiver module.  The module has been optimized for rf indicators such as transmitted power, receive sensitivity, harmonics and other key parameters.  Simplify user design.  Avoid costly equipment input  

Cost and complex debugging of RF parameters.  The user only needs to send wireless data through the six I/O ports of the single chip microcomputer and the reference driver provided by us  

Sending, receiving, RF parameter setting and other functions.
