ThumbDV™ vs PiDV™

We have received a few inquiries about the functional difference between the DV3000 and ThumbDV™.

The ThumbDV™ is a thumb or dongle type DV (digital voice) device for connection to a computer (PC, Laptop, Tablet, Raspberry Pi, Odroid, etc.) to provide access to AMBE encoding and decoding.  It is the more portable of the two devices in that you can plug it into any USB (2.0 or greater) port on a computer and access it as a serial port via appropriate software to get into the D-STAR system.

The PiDV™ is designed to use the GPIO UART pins on a Raspberry Pi (including Raspberry Pi 2 and compatible devices such as the Odroid C1)  to provide access to AMBE encoding and decoding.  It can be adapted to other similar devices using jumper wires to connect the UART, but only maps to Raspberry Pi GPIO pins.

From a software point of view they are equivalent and are accessed as serial ports (COMx under Windows,  tty? under Linux/Mac OS X, UDRx) at 230.4 kbps.  Software for using these devices includes G4KLX’s DummyRepeater,  DUTCH*Star’s Node DV (WinDV), and modified versions of DSD (developers have modified for use with the ThumbDV™/PiDV™ for monitoring DMR, Fusion, P25 Phase 2, etc. — contact the developers for more information).
