TMC2209 V2.0 stepper motor control module for 3D printer (silent)

Features: Large heat sink for optimal heat dissipation. Ultra-quiet operation. Supports sensorless return-to-home function. Supports UART mode via jumper configuration instead of soldering on MKS Gen_L V2.0, SKR 1.3/1, and MKS Sgen_L boards. UART Mode: UART mode can be used on MKS Gen_L (V2.X), MKS Sgen_L, and SKR 1.3/1.4 boards by configuring the jumper as shown below: MKS Sgen_L / MKS Gen_L. Sensorless Return-to-Home Function: Used on MKS Gen_L (V2.X), MKS Sgen_L, and SKR 1.3/1.4 boards by configuring the jumper as shown below: MKS Sgen_L / MKS Gen_L. Specifications: Default current: 1.25 A; Maximum current: 2.5 A; Logic voltage: 3.3 V/5 V; Input voltage: 5.5 V-28 V; Microstepping: up to 1/256; Modes: Direction/Step, UART; Dimensions: approximately 3 × 2 cm. Note: Observe the correct connection direction; do not reverse the connection. The motor rotation direction is reversed compared to the A4988 and DRV8825 models. Please adjust the firmware or motor wiring if you wish to modify the A4988's operation. The Dir/Step mode is used on the printer's control board. Please ensure that jumpers Ms1 and Ms2 are correctly configured. Due to variations in lighting and shooting angles, the product may have slight differences. Please note that a 0-1 cm error margin is possible due to manual measurement. Package includes: 2 TMC2209 motor drivers with heat sinks.
