Questions
How big is the Bulma PCB?
It measures 200 × 132.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bulma use?
32 parts, built around the ESP32-DEVKITC-VE, DRV8870DDAR, IRLZ44N and BZT52B13 RHG. 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 Bulma KiCad files?
From the hughminhphan/PROJECTS repository on GitHub, at the commit this page was made from: the board is Goku _ Vegeta/REDUNDANT/1.0/Bulma/Bulma.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bulma design in my own project?
Its repository states no licence, so its author keeps all rights: ask hughminhphan before reusing the design.
