Questions
How big is the BalanceRobot PCB?
It measures 73 × 78 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BalanceRobot use?
6 parts, built around the ARDUINO UNO R3. 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 BalanceRobot KiCad files?
From the yotepanda/BalanceRobot repository on GitHub, at the commit this page was made from: the board is balance_robot.kicad_pcb and its schematic balance_robot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BalanceRobot design in my own project?
Its repository states no licence, so its author keeps all rights: ask yotepanda before reusing the design.
