If you’re running the latest Debian (or even the stable one), IRC is still a good place to go for support. And there is an electronics channel on Libera that was still big last time I checked. If you don’t know which IC to use for your project someone there will probably know. I would stick around there if I were still into electronics.
Also, IRC is just more relaxing by being text-only. No flashy avatars, pictures, reactions, and for most parts no gamification.
Try Libera Chat if you like the free/libre software community. About 30’000 users connected right now.
