Questions
How big is the TurtlebotController PCB?
It measures 147 × 102 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TurtlebotController use?
169 parts, built around the TXB0104D and BUK7M12-40EX. 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 TurtlebotController KiCad files?
From the romi2002/RobottoPCB repository on GitHub, at the commit this page was made from: the board is TurtlebotController.kicad_pcb and its schematic AlternativeDrivers.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TurtlebotController design in my own project?
Its repository states no licence, so its author keeps all rights: ask romi2002 before reusing the design.
