Questions
How big is the VincentPCB PCB?
It measures 81 × 47.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VincentPCB use?
45 parts, built around the CH340C, ESP32-WROOM-32D, AMS1117-3.3 and USBLC6-2P6. 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 VincentPCB KiCad files?
From the soerengraae/Vincent repository on GitHub, at the commit this page was made from: the board is VincentPCB/VincentPCB.kicad_pcb and its schematic VincentPCB/VincentPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VincentPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask soerengraae before reusing the design.
