Questions
How big is the Etcam PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Etcam use?
86 parts, built around the FT232RL, SI8640BB-B-IS1, 74HC251D and LM1117-3.3. 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 Etcam KiCad files?
From the psychoAB/Embedded-Thruster-Control-and-Monitor-System repository on GitHub, at the commit this page was made from: the board is circuit/etcam/etcam.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Etcam design in my own project?
Its repository states no licence, so its author keeps all rights: ask psychoAB before reusing the design.
