SparkFun IoT Brushless Motor Driver (ESP32 WROOM, TMC6300)

The SparkFun IoT Brushless Motor Driver is a robust and user-friendly motor driver that can regulate any 3-phase BLDC. It comes with built-in WiFi and Bluetooth capabilities, making it an ideal choice for various IoT applications. This motor driver includes a TMC6300 from ADI + Trinamic, which is a high-performance motor driver. It allows you to control the motor using a microcontroller, like the ESP32 WROOM that comes with the board. The driver also comes with a Three Phase Brushless Gimbal Motor, ensuring optimal performance and reliability.

The TMC6300 is a potent three-phase motor driver capable of providing up to 2A (1.4ARMS) of total drive current. It allows for separate high-side and low-side control of the three half-bridges, enabling exceptional control of each motor commutation phase. The TMC6300 motor driver works well with the Arduino Simple Field Oriented Control library.

The driver also features a TMAG5273 hall-effect sensor and INA240A1 current sensor amplifiers, both manufactured by Texas Instruments. These are integrated into the IoT motor driver board design, allowing users to incorporate a position sensor and current sensing into the FOC algorithm or any feedback control loop they implement.

Moreover, the motor driver features a hall-effect sensor, three in-line current sensors for each motor phase, and a low-side current sensor. These features provide valuable information about the motor status to the user. The driver also comes with two user buttons, a Qwiic connector, and a user-configurable RGB LED for added customizability.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

The package includes an IoT Brushless Motor Driver board, a Gimbal Motor, Mounting Screws, and Motor Spacers. The board comes with a USB-C Connector, ESP32 Microcontroller, TMC6300 Motor Driver, TMAG5273 Hall Effect Sensor, Current Sensors (INA240 Current Sense Amplifier, MCP6021 Operational Amplifier), WS2812 RGB LED, 3-Pin JST Connector (to Gimbal Motor), 4 Buttons, Gimbal Motor, and Qwiic Connector.
