Product Description

The TMC2209 is a quiet and efficient stepper motor driver, ideal for 3D printers, small CNC machines, and DIY projects. Compatible with the classic STEP/DIR interface and configurable via UART (factory “jumperless” mode), the module delivers smooth motion with up to 256 microsteps (internal interpolation) and precise current control. The included aluminum heatsink helps keep temperatures low at higher currents for long-term reliability. It works with 3.3 V or 5 V logic, making it easy to integrate with most Arduino boards and modern MCUs.

Technical Details

• Driver model: TMC2209
• Maximum output current: 2 A
• Recommended continuous operating current: up to 1.7 A (with proper cooling)
• Microstepping: up to 256 microsteps (internal interpolation); HW selection via MS1/MS2
  • MS1 Low + MS2 Low → 1/8 step
  • MS1 High + MS2 High → 1/16 step
  • MS1 High + MS2 Low → 1/32 step
  • MS1 Low + MS2 High → 1/64 step
• Interfaces: STEP/DIR or UART (default support for “jumperless UART”)
• Motor supply voltage (VM): 5.5–38 V
• Logic voltage (VIO): 3.3 V / 5 V
• Pinout (reference):
  • Logic side: EN, MS1, MS2, PDN, USART, CLK, STEP, DIR
  • Power side: VM, GND, M1B, M1A, M2A, M2B, VIO, GND
• Practical features: quiet motion, advanced current control, mechanical compatibility with A4988/TMC-style carrier boards, aluminum heatsink included

Note: For high currents, use airflow and the included heatsink; set the correct RMS current via UART or potentiometer (depending on the variant) and ensure a common ground between logic and motor supply.
