Port protection for Rev7

[ian]

@electronic_eel

Is this something you already would include into the first BP7 Rev0 run, the one without the port protection stuff? Or is this for BP7 Rev1 with port protection?

Yes, sorry, you are correct, we are crossing multiple topics.

REV0 is going as is (with the poorly done TVS not populated). It is already in production, it’s a done deal.

I was following onto your REV1 push with comments about the protection parts, but this should indeed be in the other topic. Discourse doesn’t have a way to split or move posts between topics that I’ve found, or I would reshuffle a bit.

@electronic_eel

We already have a 10uF 0805 cap somewhere else. And we need a 10uF 0805 cap for the 9V aux rail.

Ah, ok I missed that the charge pump was already 0805.

@electronic_eel

For example the reset/bootloader thing will work fine with a 0402 cap, once you paired it with a matching resistor.

I saw you had already made this change and assumed you meant the remaining 10uF on the charge pump. I’m sorry for the confusion.

@electronic_eel

Which exact part number are you currently using for 4.7µF in 0402?
