SparkFun IoT Brushless Motor Driver (ESP32 WROOM, TMC6300)

SparkFun IoT Brushless Motor Driver (ESP32 WROOM, TMC6300) (ROB-22132)

The SparkFun IoT Brushless Motor Driver is an all-in-one development platform. It includes all the components to create a simple IoT device or learn about control systems. On the boaard, users will find an ESP32 microcontroller, a TMC6300 motor driver, a gimbal motor, a TMAG5273 hall-effect sensor, three INA240A1 inline current sensors, an MCP6021T low-side current sensor, two user buttons, a Qwiic connector, a 3-pin JST connector (for the gimbal motor), and a WS2812 RGB LED.

The TMC6300 from ADI + Trinamic is a powerful and easy-to-use three-phase motor driver with up to 2A (1.4A_RMS) 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. We've found the Arduino Simple Field Oriented Control library to work well with the TMC6300 motor driver.

However, a field-oriented control (FOC) algorithm requires some feedback to close and optimize the control loop. Therefore, we integrated a TMAG5273 hall-effect sensor and INA240A1 current sensor amplifiers (both manufactured by Texas Instruments) into the design of the IoT motor driver board. This allows users to incorporate a position sensor and current sensing into the FOC algorithm or any feedback control loop they choose to implement.
