Questions
How big is the CustomPCBv1 PCB?
It measures 54.8 × 60.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CustomPCBv1 use?
40 parts, built around the ESP32-S3-WROOM-1-N8, MCP3008-I/P, TPS5430DDA 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 CustomPCBv1 KiCad files?
From the Nero-gif/Linefollower repository on GitHub, at the commit this page was made from: the board is LF_3.0 - 26inter/KiCad/customPCBv1/customPCBv1.kicad_pcb and its schematic LF_3.0 - 26inter/KiCad/LinefollowerESPv3/LinefollowerESPv3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CustomPCBv1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Nero-gif before reusing the design.
