Questions
How big is the Robot V0 PCB?
It measures 50.5 × 65.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Robot V0 use?
9 parts, built around the L293D. 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 Robot V0 KiCad files?
From the teraxtech/PSH_Micromouse repository on GitHub, at the commit this page was made from: the board is robot_V0/robot_V0.kicad_pcb and its schematic robot_V0/robot_V0.2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Robot V0 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
