Spin Semiconductor

Did a new hardware setup with the SPIN mounted on a daughter board. Everything works, but I still can't say for sure what went wrong in the original scenario. Thank you everyone for the help and suggestions!

No problem. You misunderstand me though
I mean what size capacitor do you use together with your crystal? The capacitor between X2 and GND.

Alright. So I've drawn up a new PCB and sent the files for manufacturing. Received another batch of crystals from Tayda, and also bought a few from Bitsbox. What size do you use for your crystal capacitors?

Things to try are clean any flux, some are conductive and will cause problems. Try different sized caps on the crystal, try a different crystal, make sure all voltages are correct.

I've been over all this. Could you recommend a crystal supplier?

I know this is an old thread, but I seem to have a similar problem. Constant light on the CLIP LED, no audio output (in both internal and external mode), tried different crystals and different crystal cap sizes. Chips bought from Profusion (EU).

Was the issue ever resolved?
