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

The single band (UHF) version

Currently the following DV modes are supported:

• D-Star
• DMR+
• DMR BrandMeister
• C4FM

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 + RaspberryPI/OrangePi/BananaPi/Cubie + the MMDVMhost application
• DVMEGA + RaspberryPI/OrangePi/BananaPi/Cubie + 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
