Overview

The Smart BLDC Motor Controller is a compact, high-efficiency motor control solution that integrates:

• A single-cell Li-Ion charger
• Step-up converter enabling 12V motor operation from a single lithium battery
• A protected 1 Ampere BLDC motor driver
• A MEMS-based inertial measurement unit (IMU)
• A microcontroller
• An OLED user interface

All of this is packed into a tiny 28mm diameter dual-board design.

My Contribution to the Project

I joined the project at a late stage, when it was facing long-term stability and manufacturability issues. I resolved these challenges by:

• Developing test firmware (C11)
• Optimizing and verifying the power stage using simulations and handmade prototypes
• Fixing schematic issues and completely redesigning the PCB layout (Altium Designer)
• Creating Python helper and simulation scripts
• Automating BOM and fabrication documentation generation

As a result, the redesigned device has successfully passed multiple production batches without issues.
