- You need to use Monacor PG-204P and PG-203P or compatible TRS connectors (2 solder lugs and a big tab for the sleeve connection)
- Cut the 2.5mm and 3.5mm TRS sleeve tab where the hole is located
- Put both TRS connectors into the solder guide (or a cheap HT that you don't mind potentially damaging). Make sure, that they are seated all the way in
- Solder sleeve tab on the back side for both TRS connectors first
- Turn around PCB and solder remaining solder lugs
## How To Program
- Short outermost pins on the programming header. This will set the device into bootloader mode in the next step.
- Connect USB-C cable to the AIOC PCB
- Use a tool like dfu-util to program the Release Binary like this (see more information at https://yeswolf.github.io/dfu/):
````
dfu-util -a 0 -s 0x08000000 -D aioc-fw.bin
````
- Unplug and replug the device, it should now enumerate as the AIOC device
## How To use with Direwolf for APRS
- Follow the regular setup guide with direwolf to determine the correct audio device to use
However my previous experience is, that the Android kernel brings support for ttyACM devices (which is perfect) so implementing this feature should be no problem.
