Questions
How big is the HaflingerUart PCB?
It measures 43.3 × 32.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HaflingerUart use?
63 parts, built around the STM32F103C8T6, TJA1051T/3/1J, UCC27517DBVR-TP and AMS1117-3.3. 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 HaflingerUart KiCad files?
From the probstn/coolcontrol_hwstm32 repository on GitHub, at the commit this page was made from: the board is HaflingerUart.kicad_pcb and its schematic HaflingerUart.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HaflingerUart design in my own project?
Its repository states no licence, so its author keeps all rights: ask probstn before reusing the design.
