I am having trouble finding good documentation on how to wire the cm108 to a 2023model 888. These models appear very different from older versions, any help would be appreciated.
i googled the ‘2023 baofeng 888s’ radio for a picture.
it looks like it has a standard ‘kenwood’ style speaker/mic jack setup.
so, in theory, the kenwood/uv-5r digirig cable should be the ticket.
if you’re hombrewing from scratch components, the uv-5r spk/mic jack is pretty well documented.
the only ‘real’ difference between kenwood is the baofeng has a ground on both ‘pins’.
good luck

I am not using a uv5r, I am using a Baofeng 888, I do however have some uv5r radios laying around. I have not seen this digirig cable, does this just plug from the radio to the pi? Forgive my questions, I am completely new to this subject and only just started this project.
There is a basic audio cable to the sound card for K1 connectors:
However to run digital modes you’ll also need a way to key up the radio and VOX in your Baofeng is not a good option. For that reason you’ll need a proper digital modes interface such as Digirig Mobile or Digirig Lite. These models work with the audio+PTT cable from Baofeng/K1 kit:
I’m sorry i wasn’t very clear.
what i was trying to say;
it looks like the 888s has the same spk/mic connector as the uv-5r.
so, you can use/reference the uv-vr wiring diagrams that abound on the internet for your homebrew project.
as Denis posted, there is a premade cable available for that style of spk/mic connector.
commonly referred to as a K1 (kenwood).
in the topic title, it says mode-allstar
is that what you’re wanting to run?
there are quite a few tutorials online for modifying a cm108.
there is probably one describing the K1 jack setup as well.
otherwise, Denis has touched on the very capable, ready made solutions.
for allstar-link, you’d want the digirig lite as it has the gpio ptt setup already and if i remember correctly, that is the most common use with the allstar-link distro.
(i used a parallel port ptt on one my g.e. mastr nodes)
good luck

Thank you for the information. I did find the cable available, I have been able to modify the cm108 with no problem, however the problem I am having is every tutorial I have found refers to the older 888s radios, I have referenced uv5r as well and not had much luck as every video and online tutorial is not descriptive in where to solder to or what to use for components. I ordered a old 2012 version of the 888 from ebay and will have it tomorrow, I will go from there to see how that works.
