1. An overview of the

The JRF-P30TRX1 module adopts 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, reception sensitivity, harmonics, heat dissipation and other key parameters. Simplify user design. Avoid costly equipment input costs and complex rf parameters debugging. Users only need to send and receive wireless data and set RF parameters through the 6 I/O ports of the single chip microcomputer and the reference driver provided by us.

2. Basic Features:
