BIGTREETECH TMC2208 V3.0 UART Stepper Motor Driver

The BIGTREETECH TMC2208 V3.0 is a high-performance stepper motor driver designed for 3D printers and CNC machines. Equipped with advanced features like ultra-quiet operation and UART communication, it provides smooth and silent motion in all your projects.

• Buit-in Drive Current: 1.2A (2A peak)
• Microstepping: Up to 256 microsteps per full step (with interpolation)
• Voltage Range: 12V–24V DC
• Low RDSon: LS 280mΩ & HS 290mΩ (typ. at 25°C)
• Ultra-Quiet: Features stealthChop2 technology for nearly silent operation
• High-Speed Mode: spreadCycle mode for high dynamics and performance
• Single Wire UART: Enables advanced configuration directly from firmware
• Standalone Pulse Generator: For flexible application requirements

Main Features

• Configurable motor current and microsteps via firmware (UART mode)
• Dynamic switching between stealthChop2 and spreadCycle via UART
• Reduces standby current automatically for energy efficiency
• Easy potentiometer adjustment for manual current settings (STEP/DIR mode)
• Compatible with most 3D printer control boards
• Compact size: 20.32mm x 15.24mm x 10.54mm (without heatsink)
• Includes heatsink for improved heat dissipation

Modes of Operation

• STEP/DIR Mode: Plug-and-play; microsteps and current set by jumper and potentiometer
• UART Mode: Full control of driver settings (current, microsteps, chopper mode) via firmware and mainboard

Potentiometer Adjustment Instructions

• Rotate clockwise to reduce Vref and motor current
• Rotate counterclockwise to increase Vref and motor current
• Vref range: 0V – 2V (default: 1V ±0.2V)
• Always adjust while powered with 12V or 24V

Firmware & Compatibility

Compatible with popular open source firmware like Marlin (Marlin-bugfix-2.0). Supports both UART and standalone (plug-and-play) operation. Recommended for use with BIGTREETECH SKR series and similar mainboards.

Package Includes

• 1x BIGTREETECH TMC2208 V3.0 Driver Module
• 1x Heatsink
•  

Notes:

• Ensure correct orientation and alignment when installing the driver to prevent damage
• Always provide adequate cooling (heatsink and fan recommended)
• For UART mode: careful soldering may be required to bridge pads
• Incorrect wiring or installation may damage the driver or your mainboard
