Excellent Noise Reduction: The tmc2209 v2.0 stepper motor driver offers exceptional noise reduction, ensuring a quiet operation. Full Compatibility with TMC2208: The 2.5a uart silent drivers stepsticks is a replacement for the TMC2208, providing all the same functionalities. Enhanced Heat Dissipation: Equipped with a large heat sink, the silent stepsticks drivers offers excellent heat dissipation capabilities, ensuring optimal performance. Sensorless Feedback Support: The ultra silent stepsticks with heatsink supports sensorless feedback functionality, eliminating the need for additional sensors. UART Mode Support: By simply adding a jumper cap instead of soldering, the 2.5a stepstick silent driver can be easily configured to support UART mode on Gen_IV2.0, SKR1.3/1.4, and MKS SGen_L boards. The tmc2209 v2.0 stepper motor driver is designed for high performance and efficiency. With a compact size of 20.00x15.00x11.00mm, it operates at a default current of 1.25a and can handle a maximum current of 2.5a. It supports a logic voltage of 3.3v/5v and an input voltage range of 5.5v-28v. The microstepping capability goes up to 1/256, making it suitable for various applications.
