Questions
How big is the DRSSTC strap PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DRSSTC strap use?
17 parts, built around the ATTINY202-SSN. 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 DRSSTC strap KiCad files?
From the chrogoma2/DRSSTC_strap repository on GitHub, at the commit this page was made from: the board is DRSSTC_strap/DRSSTC_strap.kicad_pcb and its schematic DRSSTC_strap/DRSSTC_strap.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DRSSTC strap design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
