DDeGonge/OS-ARM
This arm is not industrial and it will not be fast, but that is not my goal. But it will hopefully be a very nice looking arm fully capable of 6dof motion, cheap enough to keep it accessable but capable enough to…




27 parts, built around the AP2112K-3.3. 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.
From the kiopity81/stm32devboard- repository on GitHub, at the commit this page was made from: the board is pcb/stm32_devboard.kicad_pcb and its schematic schematics/stm32_devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask kiopity81 before reusing the design.
