Questions
How big is the SelfBalancingRobot PCB?
It measures 51.3 × 43.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SelfBalancingRobot use?
39 parts, built around the ESP32-S3-MINI-1-N8, DRV8833PWP, AP2112K-3.3 and MPU-6050. 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 SelfBalancingRobot KiCad files?
From the stoneoxmike/SelfBalancingRobot repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SelfBalancingRobot design in my own project?
Its repository states no licence, so its author keeps all rights: ask stoneoxmike before reusing the design.
