Questions

How big is the PolicyBadge25 PCB?

It measures 90.4 × 89.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PolicyBadge25 use?

68 parts, built around the K2-1109DF-E4SW-04, HS96L03W2C03, IP2312-4V35 and TCA9555PWR(UMW). The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the PolicyBadge25 KiCad files?

From the mosfet0/policyatdc33 repository on GitHub, at the commit this page was made from: the board is PolicyBadge/PolicyBadge25/PolicyBadge25.kicad_pcb and its schematic PolicyBadge/PolicyBadge25/PolicyBadge25.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PolicyBadge25 design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
