BTT TMC2209 V1.3 5PCSPackage comes with 5 pieces BIGTREETECH TMC2209 stepper motor drivers and heatsinks. Continuous current of TMC2209 V1.3 reach up to 2.0A (peak 2.8A). Its voltage ranges from 5.5V to 28V and the microstepping capability can go up to 1/256, providing precise control over the stepper motor's movement. BTT TMC2209 V1.3 supports UART, STEP/ DIR Mode. Ultra-silent Stepper Motor DriverBIGTREETECH TMC2209 V1.3 adopts stealthChop2 Mute technology to reduce motor noise to the point of silence, ensuring noiseless operation, maximum efficiency and best motor torque. BTT TMC2209 V1.3 offers you the most cost-effective choise to upgrade your stepper drivers from non-silent TMC2100 / A4988 / DRV8825 / LV8729. No Losing StepsThe Spreadcycle provides high-precision cycle-by-cycle current control for dynamic motion. And StallGuard4 technology provides sensorless homing and load detection to prevent potential abnormal motor rotation such as skipped
