  • MULTI-MODE DIGITAL VOICE MODEM: Build a flexible amateur radio digital system with support for DMR, D-STAR, YSF/C4FM, P25 Phase I, NXDN 4800, POCSAG and analog FM. One modem board supports multiple digital voice modes for different radio projects
  • BUILD A REPEATER OR HOTSPOT: Designed as the modem core for building a digital repeater or high-powered hotspot with external radio equipment. Use one external radio for a simplex hotspot, or two radios plus a duplexer for a full-duplex repeater configuration
  • GPIO OR USB HOST CONNECTION: Connect the STM32-DVM(405 RPT) to a Raspberry Pi or compatible single-board computer through GPIO serial (UART) or USB serial using the onboard PL2303 interface. Only one host interface should be configured at a time
  • 460800 BAUD AND DUAL-SLOT DMR: Uses a 460800 baud serial connection and supports dual-slot DMR for mini digital voice repeater applications. The board supports VHF/UHF operation according to the frequency capabilities of the external radio used with the system
  • DIY RADIO PROJECTS COMPATIBILITY: Integrates with MMDVMHost-based setups including WPSD/Pi-Star and supports Raspberry Pi 3B, 3B+, Pi Zero, Pi 4 and Pi 5, plus compatible SBC platforms such as NanoPi NEO and Orange Pi. ECS TCXO provides a stable reference for low-BER-oriented digital operation
  • EXTERNAL RADIO INTERFACE REQUIRED: This is an MMDVM modem board that interfaces with external radio equipment to create a complete digital voice system. External radio hardware, host computer, appropriate cables and other system components are required for operation
