The MMDVM Digital Trunk Board (STM32-DVM 405 RPT) is a GPIO/USB-based repeater/hotspot board that connects to your Raspberry Pi (or compatible SBC) via the GPIO serial interface (UART) or USB. It runs at 460800 baud and supports both digital and analog FM modes.
Only one model available: STM32-DVM(405 RPT) — 460800 baud.

Since the release of the MMDVM in early 2016, Johnathan Naylor's (G4KLX) creation has put the power back into the hands of radio operators around the world. This simple hardware and software combo can interface radios to a computer—like a Raspberry Pi—turning normal analog radios into digital radios.
After following this guide, you will be able to put together a multimode amateur digital repeater or high-powered hotspot that can be connected to the internet for worldwide digital communication.
SXceiver is a software-defined radio transceiver optimized for the 70 cm (430–440 MHz) amateur radio band.
Sold as a kit, SXceiver includes a printed circuit board with all SMD components pre‑mounted, and a through‑hole pin header for Raspberry Pi connection.
