The SparkFun 3-Phase Brushless Motor Driver, featuring the TMC6300 from ADI + Trinamic, is a powerful and easy-to-use three-phase motor driver that was designed to control our Brushless Gimbal Motor. It can be used to control any 3-phase BLDC or PMSM motor with up to 2A (1.4ARMS) of total drive current. Separate high-side and low-side control of the three half-bridges allows for incredible control of each phase of the motor commutation. The driver also provides temperature and short circuit protections, and a diagnostic output to indicate system faults. With a 1.8V regulated power output and an operating voltage down to 2V, the TMC6300 is suitable for low-power microcontroller and battery-powered designs (min. two AA/NiMh cells, or one to two Li-Ion cells).
Our board layout has been designed with the LEDs and labels facing up, IC down. This allows the thermal pad on the board to be accessed if cooling is required. Additionally, the breakout pins are specially aligned to fit perfectly onto a breadboard and hold the headers more perpendicular to facilitate assembly.
Controlling 3-phase motors is not trivial and this board requires six PWM signals to fully control one motor. We've found the Arduino Simple Field Oriented Control library to work well with the board; however, there are some hardware limitations such as supported microcontrollers for 6PWM Mode. With additional considerations, for integrating position sensors into the feedback control loop.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- commutation
- Commutation is the process of switching power through the motor coils at the right time to keep the motor turning. In brushless motors this is handled electronically, so the quality of commutation affects smoothness, noise, efficiency, and control at different speeds.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
