TMC2209 Silent Stepper Driver, TMC2208 Replacement for A4988, TMC2225 TMC2226 Driver Modules for 3D Printer

High-concerned chemical : none Type : Module Origin : Mainland China Condition : New

This listing is for high-performance, ultra-quiet stepper motor drivers designed as direct replacements for noisier drivers like the A4988 in 3D printers (commonly used with NEMA 17 42mm motors like 17HS4401, 17HS3401, etc.). Product Models & Key Specifications: TMC2208: Output Current 1.4A (Recommended 1.2A), 256 Microsteps, Operating Voltage 5-36V. TMC2209: Output Current 2.0A (Recommended 1.7A), 256 Microsteps, Operating Voltage 5.5-38V. TMC2225: Output Current 1.78A (Recommended 0.8A), 256 Microsteps, Operating Voltage 5-36V. TMC2226: Output Current 1.78A (Recommended 0.8A), 256 Microsteps, Operating Voltage 5.5-38V. Features: Ultra-Quiet Operation: Advanced StealthChop2 technology drastically reduces motor noise and vibration. High Current & High Microstepping: Supports up to 2A and 1/256 microstepping for smoother, more precise movements. Dual Interface: Configurable via simple STEP/DIR pins or UART for advanced control (like changing settings via firmware). Wide Voltage Range: Compatible with common 12V/24V 3D printer power systems. Easy Current Adjustment: Fine-tune the output current (Vref) via the onboard potentiometer with a screwdriver. Pin Configuration (for motor connection): Coil A: Connect to pins 1A and 1B. Coil B: Connect to pins 2A and 2B. Important Usage Notes: Correct Orientation: Ensure the driver is inserted correctly on the board. Incorrect insertion will cause damage. Vref Measurement Safety: Always disconnect the motor and power the main board (not just USB) when measuring the Vref voltage between GND and the potentiometer's center pin to avoid driver burn-out. Adjustment Procedure: Power OFF the printer before adjusting the potentiometer. Adjust, then power ON to measure Vref. Heat Management: The driver can get hot. Use the provided heatsink and ensure proper case cooling (fan) to prevent overheating and ensure stable operation. Jumper Caps: When used on most 3D printer mainboards (like MKS), keep the 3 jumper caps below the driver socket in place for proper operation. Current (Vref) Adjustment Guide: Turn the potentiometer Counter-Clockwise to increase Vref and motor current. Turn the potentiometer Clockwise to decrease Vref and motor current. Formula (Typical): I_rms ≈ Vref * 0.71 (or as per your board's specific reference). For example, a Vref of ~1.0V sets I_rms to ~0.71A. Always confirm the correct formula for your specific mainboard. UART Mode Compatibility: These drivers support UART mode for firmware configuration (e.g., in Marlin, Klipper) on compatible boards like MKS GEN-L (V2.x) and MKS SGEN-L. Use jumper caps on the specific pins as per your board's manual to enable UART. Package Includes: 1x Stepper Motor Driver (Model as selected) 1x Heatsink
