Digirig Lite rev 1.2 – a minimalistic USB digital modes interface for amateur radio.

 

Description

A minimalistic version of Digirig with the same audio code as regular model of the interface but without serial port.

  • combines audio codec and PTT switch
  • supports PTT by GPIO3 of CM108 audio codec
  • supports VOX PTT by the tone on the unused right channel (experimental)
  • works with all major OS flavors: Windows, MacOS and Linux
  • uses a single TRRS connector compatible with existing Digirig audio cables
  • growing collection of pre-made cables including popular Icom, Yaesu, Elecraft, Baofeng, Xiegu transceivers
  • isolation can be easily added using inexpensive USB isolator dongle

Discussion and software configuration examples can be found in this thread.

Change log:

1.0 – Initial release, PTT by GPIO confirmed working by multiple testers with a range of apps. PTT by tone circuitry found to be not robust and therefore disconnected.

1.1 – Reduced current limiting resistor in PTT line to accommodate existing Digirig cables with resistors already in them. Improved PTT by tone on the right channel – now works with a range of software and apps, but considered experimental at this point.

1.2 – Switched form factor to a USB-C cable with USB-A adaptor included, added indicators for power and PTT, significantly improved PTT by tone/VOX. Solder pads for individually disabling PTT by GPIO3 and VOX. Pad easy access to codec’s GPIO lines used for COS and CTCSS.
