Questions
How big is the LogicPCB PCB?
It measures 65.6 × 64.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LogicPCB use?
69 parts, built around the ATMEGA2560-16AU and DRV8871DDA. 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 LogicPCB KiCad files?
From the try-except/TitoSync repository on GitHub, at the commit this page was made from: the board is LogicPCB/LogicPCB.kicad_pcb and its schematic ActiveLoad/ActiveLoadPCB/ActiveLoadPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LogicPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask try-except before reusing the design.
