interesting. so, i just got back from shenzhen maker faire, and a visit to huaquiang road markets. there's one very enterprising - and really very busy - guy in the corner of one of the buildings who, when i said "if i make some PCBs would you be interested to stock and sell them" he said "sure". his stall - as well as several others - have the bluepill.

so.

that's one possible outlet and he has several westerners visiting him because he's known to either have stuff in stock, or he and his brother can order it for you. i think he's a really good person to know. so! once this board is up and running i'll make sure he gets some to sell.

How many free holes along the edges you get when you insert it into a solderless breadboard?

Thanks!

Yes, 2 layers, 6 mils trace width / 6 mils spacing, 6 mils annular ring and 12 mils (~0.3 mm) min holes, passed DRC/ERC!

It is the same form factor and pinout as the "original" BluePill, i.e. 2.1" x 0.9".

that's then 24mil vias?
i think most cheap services specify 25/27 mil vias with 12 mil drill (although, a service like dirtypcb probably will just build it like that, some others may actually refuse it from what i heard)
i'm very curious to see how you routed all that XD. (and glad someone else is helping out, i've got too many electronics projects happening ^^'. it's becoming a fulltime job)

I used SeeedStudio Fusion PCB Service with these specs, 0.3 mm min hole + 6 mils OAR, $15.05 for 10 panels of 5 PCBs (fitted on 10 cm x 10 cm):
