This is an Arduino Nano clone I made in late May 2018. It was pretty much solely designed so that I could learn KiCad and SMD soldering, but I also kind of wanted an Arduino made in KiCad anyway.

Questions
How big is the DerTempomat PCB?
It measures 40.6 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DerTempomat use?
67 parts, built around the ATMEGA328P-AU, LM1117-5.0, MCP23S17-E/SO and MMBT3904. 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 DerTempomat KiCad files?
From the cybaer/derTempomat repository on GitHub, at the commit this page was made from: the board is Hardware/dd.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DerTempomat design in my own project?
Its repository states no licence, so its author keeps all rights: ask cybaer before reusing the design.
