Questions
How big is the CTC CU PCB?
It measures 80 × 92 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CTC CU use?
78 parts, built around the ATMEGA324A-PU and AM26LS31CD. 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 CTC CU KiCad files?
From the MichaelPrader/sig-ctc-CU repository on GitHub, at the commit this page was made from: the board is pcb/CTC-CU.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CTC CU design in my own project?
Its repository states no licence, so its author keeps all rights: ask MichaelPrader before reusing the design.
