Tidy up design documentation for open-sourcing #8

Open amcewen opened 3 months ago

amcewen commented 3 months ago

A small addition to make to the schematic to better explain how the antenna is included:

Do we need to label p200/p202 or J411 on the silkscreen?

Equally J400, J401, J402, J403, J406, J407, J408. Do they need labelling, or documenting somewhere?

amcewen commented 3 months ago

By labelling, do you mean "add extra explanation of what they are"?

I'm not sure we need to on the silkscreen, but it'd be useful to have that info noted down somewhere in the documentation. P200 and P202 are optional mosfets for extra load when being used for card emulation, IIRC. And the assorted J points are mostly test points, I think?

Hopefully @larchard will be able to provide a brief note (a sentence on them would likely be enough?) to include in the README.md.

huffeec commented 3 months ago

Yes, I thought it would be the case. I may or may not be trying to get the gerbers finalised today so we have a pi day revision number...

larchard commented 3 months ago

I'm out today, currently in a Spoons with a laptop on very low battery and without KiCad. If @amcewen can WhatsApp an image of the relevant bit(s) of the schematic, I'll try to comment.

I don't think there is anything urgent. I've got what I need for the silkscreen, and can add to to documentation after we've submitted to OSHW. Certainly not worth getting curry on a laptop for...

Damn. I was so distracted ordering 1/3 pints of the beer festival specials that I forgot it's Curry Club day.
