Questions
How big is the LineFollower V2 PCB?
It measures 120 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LineFollower V2 use?
146 parts, built around the DRV8872DDAR, LMR36015FBRNXT, LM358 and LF33CDT-TRY. 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 V2 KiCad files?
From the degesz/LineFollower_PCBs repository on GitHub, at the commit this page was made from: the board is KiCAD Boards/LineFollower_V2/LineFollower_V2.kicad_pcb and its schematic KiCAD Boards/LineFollower_V2/1_MCU core.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LineFollower V2 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
