Questions
How big is the Dashboard PCB?
It measures 145 × 73 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dashboard use?
284 parts, built around the STM32F103C8T6, 74HCT541D, SN65HVD230D and ADP2303ARDZ-5.0. 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 Dashboard KiCad files?
From the broncoracing/dashboard repository on GitHub, at the commit this page was made from: the board is pcb/PCB.kicad_pcb and its schematic pcb/5v3A_reg.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dashboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask broncoracing before reusing the design.
