MMDVM Digital Voice Modem Board with Cable

Add a modem board to an appropriately configured amateur-radio project. This MMDVM accessory works with compatible host hardware and software. It is for competent radio users checking interfaces, firmware and permitted operation.

• ✅ Build a modular setup — The board is a separate modem component.
• ✅ Use a host-based workflow — Compatible development hardware runs the required software.
• ✅ Prepare the connection — A connecting cable is included.
• ✅ Choose a multi-mode project — D-Star and DMR are described within the supported setup.

Match the host and radio interface together

Raspberry Pi and Pi-Star references require the correct hardware connections and software configuration. Not every radio or board is interchangeable.

The pack contains one module and cable, not a complete repeater or radio. Check mode-specific requirements and operate within the applicable radio authorisation.
