The project is still empty; no schematic or PCB changes were made because no ACUs are currently available.

Remaining decisions include motor type and voltage/current, sensorless vs Hall/encoder feedback, control interface, and preferred STM32 family. Once ACUs are available, the design can proceed with dedicated three-phase gate drivers and MOSFETs, current/voltage sensing, protected feedback inputs, and a separate free I²C bus for external sensors.
