Specification Brand : Geeetech BulletPoint1 : Supports UART & STEP/ DIR: Geeetech TMC2209 with heat sink. Supports UART mode by set jumper caps, Our TMC2209 also has standard STEP/ DIR interfaces for easy use.The large-area fan thermal pad will improve heat dissipation of the driver. BulletPoint2 : Support STEP/DIR or UART Mode: The TMC2209 stepper driver is known for its quiet operation, making it ideal for 3D printing applications where noise can be distracting or distracting. Say goodbye to noisy printing. BulletPoint3 : More Accurately: The TMC2209 stepper motor driver provides high accuracy and smooth operation, resulting in improved 3D printing performance. Ensuring better print quality and fewer print errors.Stall detection with indicators BulletPoint4 : Versatile Compatibility: 3D printer stepper driver modules can be used with a wide variety of stepper motors commonly used in 3D printing, making it a versatile option for hobbyists who want to experiment with different motors or upgrade their existing setup. BulletPoint5 : Stable Performance: CoolStep technology allows the 3d printer tmc2209 to control the current dynamically, in order to adapt the motor current for excellent efficiency and low heat-up of motor and driver. Four-layer board welding process ensures stable performance.

It supports larger up to 2.8A and allows a maximum subdivision of 256, and infinitely zeroing. Product Name: TMC2209 driver Native Microsteps: up to 256 Peak Current: 2.8A Confguration: STEP/DIR and UART mode Factory Default Current: 1A Voltage: 4.75 - 29V IC Logic Voltage: 3.3/5V Effective Current: 2A Application: 3D printer main control board Weight: 3g FEATURES 1. The motor is not easy to lose its position, which improves printing quality; 2. Ultra- silent mode; 3. Large fan thermal pad improves heat dissipation of the driver; 4. Effectively prevent motor jtter to print more accurately; 5. Four-layer board welding process ensures more stable performance; 6. Stall detection with indicators; 7. Support STEP/DIR or UART mode 8. Easy to DIY and operate TIPS 1. Be sure to disconnect the power supply before installing the driver to prevent the driver from burning. 2. Before installing the driver, check the direction to prevent reverse connection (The reference board is the same as the module silkscreen). 3. Do not plug or unplug the driver while power is on. 4. When installing heat sink, be careful not to touch the heat sink and pin headers to prevent shorted circuit. 5. Make sure all cooling measures are ready before use (e.g. heat sink, flow air, cooling fan) 8. Use a power supply (12 or 24V DC) when measuring the voltage, do not use USB power supply only.
