Driver motor pas cu pas (stepper) TMC2208 V2.0

Product Description:

The TMC2208 V2.0 module is an ultra-silent stepper motor driver, ideal for 3D printers and other CNC applications. It uses StealthChop2™ technology for virtually inaudible operation, reducing motor noise to under 10dB. It comes equipped with a new heatsink for efficient thermal dissipation and supports up to 256 microsteps through smart interpolation.

Main Features:

• Ultra-silent technology – StealthChop2™: Operates extremely quietly, perfect for 3D printers requiring a quiet working environment.
• Dynamic chopping mode – SpreadCycle™: Provides stable current control without ripple in the zero-crossing area, resulting in smoother and more precise movement.
• Reduced heat generation: Compared to the TMC2100, the TMC2208 generates less heat at the same current, allowing the use of smaller heatsinks.
• Smart interpolation: Microsteps are extended from 16 to 256 through a differential algorithm, ensuring smooth and quiet motion even at low pulse rates.
• High-quality materials: Built with durable components for long-term stability and reliability.

Technical Specifications:

• Chip model: TMC2208
• Maximum output current: 1.4A
• Recommended current: up to 1.2A
• Factory default current: 0.7A
• Microstepping: up to 256
• Configuration mode: STEP/DIR or UART
• Motor supply voltage: 5V – 36V
• Logic voltage: 3.3V / 5V

Usage Instructions:

1. The heatsink must be attached directly to the PCB – pay attention to its orientation to avoid shorts between pins and the heatsink.
2. The motor direction is reversed compared to A4988/8825 drivers. If replacing an A4988, adjust the motor direction in firmware or by reversing the wiring.

Current Adjustment Algorithm (VREF):

1. Measure VREF between GND and the middle pin of the potentiometer.
2. Do not connect the motor during measurement – this may damage the driver.
3. Use a dedicated power supply during measurement (not just USB power).
4. Ensure the driver is inserted correctly – do not reverse the orientation!
