Minimum voltage requirement for Simulcast C100?

[mbest]

Hi All,

I just received a Simulcast and am excited to get started on it! I noticed a potential discrepancy in the build doc (v2022-12-17). The image of the PCB on page 1 suggests that C100 should be a minimum of 35V. However, the parts list does not call out that requirement unlike other caps where it's explicitly noted. Should a 35V minimum cap also be used in C100?

It's only going to see the 9V from your power supply, so anything rated 16V and up is fine.

The simulcast has a charge pump and runs at 27v. That's why it calls for 35v caps

True. C100 is before the charge pump though, so 35V is unnecessary here.
