Questions
How big is the Mkssbase PCB?
It measures 46 × 79.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mkssbase use?
55 parts, built around the MAX485ED, 74HCT04D, 74HCT08D and AMS1117-3.3. 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.
Where can I download the Mkssbase KiCad files?
From the Hal9k-dk/lasersaur repository on GitHub, at the commit this page was made from: the board is pcb/mkssbase/mkssbase.kicad_pcb and its schematic pcb/chillercontrol/chillercontrol.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mkssbase design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hal9k-dk before reusing the design.
