README
README.mdAIOLI-FOC (All In One Low I - FOC)
Small, low current (I) closed loop simpleFOC driver board, that can be assembled for <$10 with mostly basic components at LCSC. Has USB C for power, serial communication (USB CDC), and DFU firmware updates. The CANBUS peripheral is exposed on both edges for "stitching" boards together using the Kyocera B2B connector used on the STLINK-V3-MINIE. SWD + UART via STLINK 14 pin connector.
The target for this project was to create an all-in-one simpleFOC board with high resolution magnetic encoder, better MCU than the previous STM32F103, CANBUS for multi board communication, and be assembled with top-side only components. The board is 4 layers (which at this size, does not add any cost over the 2-layers). Additionally, it has a compact size of 40x40mm.

90 parts, built around the SN65HVD230D, STSPIN233, SRV05-4 and XC6206-2.8V. 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 Stm32g431-mt6701-stspin233 KiCad files?
From the VIPQualityPost/aioli-foc repository on GitHub, at the commit this page was made from: the board is hardware/stm32g431-mt6701-stspin233.kicad_pcb and its schematic hardware/display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32g431-mt6701-stspin233 design in my own project?
Its repository states no licence, so its author keeps all rights: ask VIPQualityPost before reusing the design.
