Questions
How big is the SPB PCB?
It measures 60 × 60 mm and has 4 copper layers, 1.66 mm thick.
What parts does the SPB use?
134 parts, built around the STM32F401RET6, DPS368XTSA1, MMC5983MA and MS560702BA03-50. 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 SPB KiCad files?
From the naimmas/SPB repository on GitHub, at the commit this page was made from: the board is 02_Electronics/02_PCB/SPB/SPB.kicad_pcb and its schematic 02_Electronics/02_PCB/SPB/SPB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SPB design in my own project?
Its repository states no licence, so its author keeps all rights: ask naimmas before reusing the design.
