Overview

The DV-MEGA is a family of add-on boards (shields) for Arduino Uno, Arduino MEGA and Raspberry Pi for several digital voice communication standards.
DV-MEGA is produced by Guus van Dooren PE1PLM, http://www.dvmega.auria.nl/

The dualband (VHF/UHF) version DBR UNO.png

The single band (UHF) version Dvmega sb.jpg

Currently the following DV modes are supported:

  • D-Star
  • DMR+
  • DMR BrandMeister


To utilize the DVMega hotspot, a transceiver capable of the selected DV mode is necessary to operate as the hotspot only provides a gateway into the selected infrastructure. The DV-MEGA has only one time slot.

Functionality

  • Private call
  • Group call

Soon

  • SMS
  • GPS
  • RRS/ARS

Mode of work

  • DVMEGA + Raspberry PI + the MMDVMhost application
  • DVMEGA + Raspberry PI + the BlueDV application for Android via ser2net in a hotspot mode wifi connection
  • DVMEGA + Bluestack board + BlueDV Android application that uses Bluetooth to control the DVMega

Hardware

Three different hardware configurations of DV-MEGA are currently available:

  • Dualband radioshield - Arduino UNO based Support for D-Star and DMR
  • Dualband radioshield - Arduino MEGA based Support for D-Star and DMR
  • RPi radioshield - Raspberry PI based Support for D-Star and DMR
  • RPi radioshield - Orange Pi based Support for D-Star and DMR

Software

  • dmrlib (highly experimental, for developers only)
  • BlueDV [1]
  • BlueSpot [2]
  • MMDVMHost [3]
  • ircddbgateway [4]
