Versaloon Software Framework -- a tiny preemptive-capable event-driven incremental software framework for embedded systems
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
78 parts, built around the LM324D, CH340N, LM1117-3.3 and S9013. 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.
From the Lucid-A/Digital-Thermometer repository on GitHub, at the commit this page was made from: the board is Hardware/digital_thermometer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Lucid-A before reusing the design.
