Questions
How big is the SBR2 PCB?
It measures 88 × 64 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SBR2 use?
26 parts, built around the ESP32-DEVKITC-VE. 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 SBR2 KiCad files?
From the hughminhphan/PROJECTS repository on GitHub, at the commit this page was made from: the board is Self_Balancing_Robot/SBR2/SBR2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SBR2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask hughminhphan before reusing the design.
