Questions
How big is the VolleyBot PCB?
It measures 80 × 52 mm and has 2 copper layers, 1.61 mm thick.
What parts does the VolleyBot use?
110 parts, built around the STM32F411CEU6, RZ7899-MS, AP62300TWU and IP2326. 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 VolleyBot KiCad files?
From the CausticLime1/VolleyBot repository on GitHub, at the commit this page was made from: the board is Electrical/VolleyBot.kicad_pcb and its schematic Electrical/VolleyBot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VolleyBot design in my own project?
Its repository states no licence, so its author keeps all rights: ask CausticLime1 before reusing the design.
