Sensored BLDC Controller
Sensored BLDC Controller is an open source AVR/Arduino PCB design by rjwalters: a 4-layer, 70 × 90 mm board with 42 components (23 distinct parts). It is built around the ATMEGA328P-AU, DRV8313PWPR, TPS7A1650DGNR. Filed under robotics & motion.
Standalone Python tools for parsing and manipulating KiCad schematic and PCB files
Revision B is a real 42-component, 70 × 90 mm, four-layer small-motor controller: ATmega328P-AU, DRV8313PWPR integrated triple half bridge, and TPS7A1650DGNR 5 V supply. It includes reverse-input protection, fuse, transient clamp, charge-pump capacitors, current comparator, Hall inputs, AVR ISP, RUN switch input, speed trimmer and working commutation firmware.
