Questions
How big is the Precharge PCB?
It measures 100 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Precharge use?
33 parts, built around the VRB1205YMD-15WR3, LM339, LTV-817S and SMAJ15CA. 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 Precharge KiCad files?
From the broncoracing/precharge repository on GitHub, at the commit this page was made from: the board is pcb/PCB.kicad_pcb and its schematic pcb/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Precharge design in my own project?
Its repository states no licence, so its author keeps all rights: ask broncoracing before reusing the design.
