Bela Gem, two new boards

giuliomoro

The opamps for the analog inputs and the ADC support a supply down to 3V, so I guess it should be possible if we can provide a regulated supply above 3V.

The issue is that the codec is powered from the PB2-provided 3v3 rail, which is on an LDO from the input voltage. So if your input is 3.2V, the 3v3 line will actually be something like 2.9V and more noisy, because the LDO won't be able to regulate properly. Things should still work - I believe - but you may have surprises.

Makes sense, thank you for the clarification.
We will do some tests and see what works best when we get the Gem.
Thank you for great support!

Congrats on this great step forward for the Bela series!

I have a similar question/request regarding the Bela Gem Multi: are schematics available? And if not, any idea when they might be? I'm working on building an expander/connected PCB of sorts & would be great if I can get the necessary dimensions tightly aligned.

Look forward to receiving the order & getting started with it 🙂
