The TMC2209 is a stepper motor driver known for its high efficiency, low power consumption, and advanced features like StallGuard4 (sensorless homing) and StealthChop2 (extremely quiet operation).
Features
- Silent operation: Features StealthChop2 for extremely quiet motor movements
- High resolution: Supports microstepping up to 1/256-step (via interpolation). Directly configurable microsteps range from full-step to 1/32-step.
- Sensorless homing: Includes StallGuard4 for detecting motor load without the need for end-stop switches.
- Dynamic current control: Uses CoolStep to dynamically adjust the motor current, which reduces power consumption and heat generation.
- Broad compatibility: Suitable for NEMA17 stepper motors, among others.
- Protection: Protection against overheating, overcurrent, and undervoltage.
- Communication: Supports UART for advanced configuration and monitoring.
