README
README.mdGetting Started with A-Team Electrical
All current board releases use KiCad 7.X.
See releases for competition production files. Our releases include known bug documentation, and the confirmed gerber, BoM, and CPL files sent to fab so you know you're looking and ordering what we did. Releases are accompanied by a tagged commit, for all editable project files used to generate the fab products.
For complex boards like control and kicker, we include spice models and python files that compute any relevant values from datasheets, and including documented references and links to needed formulations.
Setting Up KiCAD
Setting Up the KiCAD Library Path
- Click
Preferences->Configure Paths - Under
Environment Variablesclick+ - Set the name
LIB_DIR_AT - Set the path to
<repository_location>/libwhere <repository_location> is the download location.
Example entry:
- Name:
LIB_DIR_AT - Path:
C:\Users\guyfl\Documents\A-Team\electrical\lib
Setting Up JLCPCB Plugin
KiCAD version 6.99 (nightly) or newer should install the KiCAD JLCPCB Tools plugin.
Setting Up the Python Environment
- We recommend creating a python environment using
python3 -m venv venv(python 10 appears to be required) - Install poetry
pip install poetry - Run any python file with
poetry run python <python_file> - (Optional) Add dependencies with
poetry add <dependency>
Soldering
Our soldering process is documented. Advanced components like modern SMPS chips and current sense motor hardware proved sensitive to technique. The team's tries to PCBA as much as possible, but sometime it's too expensive to PCBA all chips, especially advanced ones not in stock at the fab house.

Questions
How big is the Motor controller PCB?
It measures 45 × 46 mm and has 6 copper layers, 1.53 mm thick.
What parts does the Motor controller use?
106 parts, built around the STSPIN32F0B, AS5047P-AT, STL90N10F7 and 06F-0200L1. 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 Motor controller KiCad files?
From the SSL-A-Team/electrical repository on GitHub, at the commit this page was made from: the board is robot/motor-controller/v1.1/motor-controller/motor-controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motor controller 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).
