README
README.mdElectrical
This is a repository containing all of the electrical board designs of The Bots, including firmware for the chicker board, which is contained in that sub-folder.
The robot contains five custom PCBs (not including the Raspberry Pi).
All five boards contained on our robot (six including the Raspberry Pi), for context, are listed as follows:
- Raspberry Pi 4 - Main Robot Computer and link between the active running computer running our team's software
- Faceplate - Connector between Raspberry Pi and Midplate for CANBUS communication, peripherals, and LCD screen eyes
- Midplate - Battery input and power distribution (doubles as a mechanical chassis)
- Chicker - High Voltage Flyback Capacitor Charger and Solenoid Driver
- Simovr - A BLDC Motor Driver designed based on the Tinymovr platform in a smaller footprint
- Baseplate - Power distribution and CANBUS distribution for the Simovr's, and breakbeam circuits to detect the ball

Questions
How big is the FacePlate PCB?
It measures 129.6 × 45 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FacePlate use?
59 parts, built around the SN65HVD233D, AMS1117-3.3, MCP2515T-I/ST-HX and CC0603KRX7R9BB104. 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 FacePlate KiCad files?
From the sfunderbots/Electrical repository on GitHub, at the commit this page was made from: the board is FacePlate/FacePlate.kicad_pcb and its schematic BasePlate/BasePlate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FacePlate design in my own project?
Its repository states no licence, so its author keeps all rights: ask sfunderbots before reusing the design.
