The RV-M8 series of OEM radio modems is configured to easily be integrated into OEM products.

The 20 pin UWORC connector is a standard data radio modem pin out used on all Raveon OEM radio modems.

A PDF describing the UWORC is here.

The 20-pin connector has male pins to plug into your PCB.

The male connector on the radio modem is a 20-pin 2mm header.


This Radio with the UWORC connector is easy to design into your product.  A;; Raveon OEM radios use this connector pin-out so you can use any or all of our radios in you rroducts.

The following table details a UWORC’s pin function and detailed implementation on supported hardware:

Pin No. Name I/O Type M8 M8/M6 Daisy(VHF, UHF, UHF+) D50/Z50Daisy
