Questions
How big is the M2MRover PCB?
It measures 80 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the M2MRover use?
61 parts, built around the L298HN, LD1117V33 and LD1117V50. 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 M2MRover KiCad files?
From the SoftwareCornwall/Mission-to-Mars-Rover repository on GitHub, at the commit this page was made from: the board is KiCad/M2MRover.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the M2MRover design in my own project?
Its repository states no licence, so its author keeps all rights: ask SoftwareCornwall before reusing the design.
