Questions
How big is the Logic PCB?
It measures 90 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Logic use?
177 parts, built around the 74AHC541D, SN65HVD232D, CY7C65213-32LTXI and W25Q16JVSSIQ. 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 Logic KiCad files?
From the nodevuser197/astobot-logic repository on GitHub, at the commit this page was made from: the board is logic.kicad_pcb and its schematic Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Logic design in my own project?
Its repository states no licence, so its author keeps all rights: ask nodevuser197 before reusing the design.
