Questions
How big is the Logic PCB?
It measures 184.1 × 175.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Logic use?
74 parts, built around the M78AR05-0.5 and RK73B2ATTD102J. 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 open-rdc/Bipedal_Robot_Hardware repository on GitHub, at the commit this page was made from: the board is Circuit/Kicad/V1/logic/logic/logic.kicad_pcb and its schematic Circuit/Kicad/V1/logic/logic/logic.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 open-rdc before reusing the design.
