Questions
How big is the PCB PCB?
It measures 58 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB use?
30 parts, built around the STM32F030F4P6, DS18B20, TL494 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 PCB KiCad files?
From the Aborav/PCB_VAW_Meter repository on GitHub, at the commit this page was made from: the board is PCB_.kicad_pcb and its schematic PCB_.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aborav before reusing the design.
