Questions
How big is the RobotHat PCB?
It measures 65 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RobotHat use?
50 parts, built around the ATMEGA328P-AU, LM2596S-5.0, AO3401A and SS34. 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 RobotHat KiCad files?
From the aliaafee/robot-platform repository on GitHub, at the commit this page was made from: the board is schematics/RobotHat/RobotHat.kicad_pcb and its schematic schematics/MotorDriver2/MotorDriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RobotHat design in my own project?
Its repository states no licence, so its author keeps all rights: ask aliaafee before reusing the design.
