Questions
How big is the Control Module PCB?
It measures 93 × 171 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Control Module use?
123 parts, built around the MP2338GTL-Z, SN74LVC1G14DBVR, CY74FCT163CTSOC and SN74AHC74DRE4. 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 Control Module KiCad files?
From the SSCsimsi/8Bit_Computer repository on GitHub, at the commit this page was made from: the board is 8Bit Computer ver2.0/Kicad/Computer/Control_Module.kicad_pcb and its schematic 8Bit Computer ver2.0/Kicad/ClockGen/ClockGen.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Control Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask SSCsimsi before reusing the design.
