Questions
How big is the Hedgehog PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hedgehog use?
144 parts, built around the STM32F401VBT6, MC74VHC1G126P5, DRV8835DSS and RT7259GQW. 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 Hedgehog KiCad files?
From the PRIArobotics/Hedgehog_PCB repository on GitHub, at the commit this page was made from: the board is Hedgehog.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hedgehog design in my own project?
Its repository publishes it under the AGPL-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).
