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.

Specifications

• Logic voltage: 3.3 V and 5 V signals
• Motor operating voltage: 5.5 V to 28 VDC
• Output current: Up to 2 A RMS (continuous current) per coil
• Peak current: Up to 2,8 A per coil
• Cooling: Requires a heatsink(included)/active cooling, especially at higher currents
