The connector breaks off of the PCB! (There’s a tiny drop of glue between the “+” and “sig” lands, down near the teeny-tiny hole, that holds it in place that failed.)
Thank the Good Lord that the solder connections fractured instead of ripping the lands off the board. THIS is something I can fix.
Huh. Looks like your pins were surface mounted. I just looked - mine are definitely through-hole. But I’m not using the servo pins, so it doesn’t really matter, at least for now.
Glad you were able to fix Charlie.
/K
PS (and completely off topic)- the notion of “getting Charlie fixed” triggered a memory of a bumper sticker I saw ~30 years ago. Instead of “I my dog”, this bumper sticker said “I my dog”. It made me laugh out loud
