MReX-PCB Message and Telemetry Mini Transmitter

The MReX-PCB is a miniature stand-alone messaging and control transceiver.

The MReX-PCB incorporates the MReX-460 telemetry module. This product provides a simple type approved solution to send POCSAG or DMR messages from any enclosure.  Many thousands of transmissions are possible before battery replacement is required.

Although this product is commonly stocked and can be supplied, the provided Gerber files (download below) can be used for own production purposes.

This is a simple method to evaluate the functionality of the MReX module.
