Tired of Programming cables that only do one thing, and do them poorly? Ditch your Baofeng Programing cable and build a AIOC (All in One Cable)

Use your AIOC to program radios AND encode/decode APRS.

In this episode I provide a brief demo on how to solder and upload the firmware for the AIOC. This project is still in development and can only get better. What changes would you like to see implemented?

From Github:
What does it do?
The AIOC is a small adapter with a USB-C connector that enumerates itself as a sound-card (e.g. for APRS purposes) and a virtual tty ("COM Port") for programming and asserting the PTT (Push-To-Talk).

Features
Cheap & Hackable Digital mode USB interface (similar to digirig, mobilinkd, etc...)
Programming Cable Function via virtual Serial Port
Compact form-factor (DIY overmolded enclosure is currently TBD)
Based on easy-to-hack STM32F302 with internal ADC/DAC (Programmable via USB bootloader using DFU)
Can support Dual-PTT HTs
Compatibility
Software
Direwolf as AX.25 modem/APRS en+decoder/...
APRSdroid as APRS en+decoder
CHIRP for programming

Tested Radios (so far)
Wouxun UV-9D Mate (CHIRP + APRS)
Baofeng UV-5R (CHIRP + APRS)
BTECH 6X2 (CHIRP)


Future Work
Overmolded enclosure design (DIY using 3D-Printed mold and Resin/Hotglue)
Maybe integrate a TNC Modem with KISS interface? (I am not sure if that is worth the effort)
"High-Performance" VOX emulation with advanced features (e.g. pre-triggered VOX to activate PTT a few milliseconds before data, reduced tail time)
HID (maybe CM108 compatible) PTT control



How To Fab
Go to JLCPCB.com and upload the GERBER-k1-aioc.zip package (under kicad/k1-aioc/jlcpcb)
Select PCB Thickness 1.2mm (that is what I recommend with the TRS connectors I used)
You may want to select LeadFree HASL
Select Silkscreen/Soldermask color to your liking
Check "PCB Assembly"
PCBA Type "Economic"
Assembly Side "Top Side"
Tooling Holes "Added by Customer"
Press Confirm
Click "Add BOM File" and upload BOM-k1-aioc.csv
Click "Add CPL File" and upload CPL-k1-aioc.csv
Press Next
Look Through components, see if something is missing or problematic and press Next
Check everything looks roughly good (rotations are already baked-in and should be correct). Save to Cart
This gives you 5 (or more) SMD assembled AIOC. The only thing left to do is soldering on the TRS connectors (see here). The total bill should be around 60$ US for 5 pieces plus tax and shipping from China.

Baofeng APRS made easy, Baofeng programming made easy, baofeng programming with chirp.
