Questions
How big is the UsbToSerial PCB?
It measures 100 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UsbToSerial use?
17 parts, built around the ATMEGA328-PU. 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 UsbToSerial KiCad files?
From the etimou/usbToSerial repository on GitHub, at the commit this page was made from: the board is hwdesign/CADfiles/usbToSerial.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UsbToSerial design in my own project?
Its repository states no licence, so its author keeps all rights: ask etimou before reusing the design.
