Questions
How big is the Controller mcu bu an 64 BIG PCB PCB?
It measures 144 × 78 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Controller mcu bu an 64 BIG PCB use?
116 parts, built around the 74HCT125PW, 74HC4067PW, 74HC138 and 74HC165D. 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 Controller mcu bu an 64 BIG PCB KiCad files?
From the Mo-MoS/controllers repository on GitHub, at the commit this page was made from: the board is s2/kicad/controller_mcu_bu_an_64/controller_mcu_bu_an_64/controller_mcu_bu_an_64_BIG_PCB.kicad_pcb and its schematic s2/kicad/analog_mux/analog_mux/analog_mux.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller mcu bu an 64 BIG PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mo-MoS before reusing the design.
