Size: As pictured Material: PCB Color: Blue Name: TMC2209 Stepper Motor Driver Module New design and high-quality product. Features: Silent Motor Operation: Thanks to StealthChop2 technology, the TMC2209 enables silent motor operation. The TMC2209 drivers operate with a continuous current of up to 2.0A, with peaks of 2.8A. Sensorless Homing: The TMC2209 incorporates StallGuard technology to detect changes in motor current, using this measurement to detect the end of a shaft's stroke and produce 3D printers without limit switches. Dynamic Current Control: CoolStep technology allows the TMC2209 to control current dynamically, enabling higher current intensities and better thermal performance, saving up to 75% of electrical energy. Supports UART, STEP/DIR Modes: The 1PCS TMC2209 V1.2 UART stepper motors support UART and STEP/DIR modes. You will need to modify the firmware for the mode you are using. Satisfactory Customer Service: If you encounter any issues with our TMC2209 V1.2 UART stepper pins, please feel free to contact us. Notice: 1. Colors may vary slightly due to different monitor displays. 2. Please allow for some manual measurement errors; thank you for your understanding. Package Includes: 1x TMC2209 V1.2/V1.3 UART Stepper Motor Driver Module
