Questions
How big is the PCB 01 PCB?
It measures 35 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB 01 use?
80 parts, built around the DFR0299, CH224K, MP1584EN and MPR121QR2. 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 01 KiCad files?
From the abxnx/PCB_Fastwork repository on GitHub, at the commit this page was made from: the board is PCB_01/PCB_01.kicad_pcb and its schematic PCB_01/PCB_01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB 01 design in my own project?
Its repository states no licence, so its author keeps all rights: ask abxnx before reusing the design.
