Circuit Learning Minibadge
The goal of the minibadge this year is to provide a platform for you to learn about basic analog electronic circuits. You'll need to acquire a kit from the HHC area, and then take it to the Solder Skills Community to assemble it. Once you have completed that, download the circuits workbook and get started on your journey.

Questions
How big is the Bhc PCB?
It measures 20.3 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bhc use?
8 parts, built around the AT24CS01-SSHM-B. 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 Bhc KiCad files?
From the hamster/SAINTCON repository on GitHub, at the commit this page was made from: the board is Bitstream Hackers/2026/bhc.kicad_pcb and its schematic Bitstream Hackers/2025/bhc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bhc 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).
