README.mdWARNING!
when i ordered a batch of these they didn't work and i have no idea why, i think the chips might just have been busted.
do not follow this design as a reference at all. i am only leaving it up for archival purposes.

Questions
How big is the Dipstick PCB?
It measures 10.2 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dipstick use?
19 parts, built around the CH330N. 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 Dipstick KiCad files?
From the mothdotmonster/dipstick repository on GitHub, at the commit this page was made from: the board is pcb/dipstick.kicad_pcb and its schematic pcb/dipstick.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dipstick design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
