Questions
How big is the Jerboa-8 PCB?
It measures 76.2 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Jerboa-8 use?
23 parts, built around the ATTINY85-20PU. 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 Jerboa-8 KiCad files?
From the strickyak/jerboa-attiny85-mod-synth repository on GitHub, at the commit this page was made from: the board is PCBs/jerboa-2024-02-29/jerboa-8.kicad_pcb and its schematic PCBs/jerboa-2024-02-29/jerboa-8.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jerboa-8 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).
