Questions
How big is the HBridge328 PCB?
It measures 50.8 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HBridge328 use?
29 parts, built around the ATMEGA328-PU. 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 HBridge328 KiCad files?
From the UserHackable/HBridge328 repository on GitHub, at the commit this page was made from: the board is KiCad/HBridge328/HBridge328.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HBridge328 design in my own project?
Its repository states no licence, so its author keeps all rights: ask UserHackable before reusing the design.
