Building an AllStarLink Node
In this post I will briefly describe my build of an AllStarLink node. For this, I used the following parts:
- Baofeng 888s
- CM108 USB soundcard
- Raspberry Pi 4 + case
- two buck converters, configured 5V and 3,7V output voltage
- metal enclosure
- power poles + mounting plates
- ethernet jack
- Waveshare LCD1602 RGB Module
I will not go into great detail here since all modifications are described in other places. Please consult the following links:

The beginning:
Please ignore the two audio transformers. I planned to install them but went with a transformerless build in the end.
Here is the modified sound fob as described in the above link:
A first test with the RPi and the buck converters built in:
