Questions
How big is the LineFollower PCB?
It measures 110 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LineFollower use?
115 parts, built around the DRV8833PWP, BX-PH2.0-2PZZ, LSM6DSV and SFH 309 FA-4. 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 LineFollower KiCad files?
From the InderveerS/LineFollower repository on GitHub, at the commit this page was made from: the board is PCB/lineFollower.kicad_pcb and its schematic PCB/display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LineFollower design in my own project?
Its repository states no licence, so its author keeps all rights: ask InderveerS before reusing the design.
