Driver board for the servo bus motors. Includes connection for LED eyes, serial control for bus servo motors, and power control for bus servo motors, with mounting spot for microcontroller dev board.
To-Do Edits for Final PCB
- Zane says we should round our pcb corners lol
- Swap the data and ground pins on the jsts so the right angle jsts can actually be connected to the board on the same side as everything else, oops
- Add a label for the transistors for the relay for the actual type of transistor
- Update PCB revision on board when updating board

Questions
How big is the SensorArduinoHat PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SensorArduinoHat use?
36 parts, built around the CD4050BE, CD74HC14E and SN74AHC86N. 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 SensorArduinoHat KiCad files?
From the shareresearchteam/SAMI-Robot repository on GitHub, at the commit this page was made from: the board is hardware/Electrical/SensorArduinoHat/SensorArduinoHat.kicad_pcb and its schematic hardware/Electrical/JamieMotorControl/JamieMotorControl.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SensorArduinoHat 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).
