BIGTREETECH TMC2208 V3.0 UART Stepper Motor Driver with Heatsink Reprap TMC2209 for Octopus V1.1/SKR 3/SKR V1.4 Turbo Manta Series MKS Gen L 3D Printer Motherboard（1pcs）

• 【Smooth Operation】:Incorporated the Spreadcycle technology, BIGTREETECH TMC2208 stepper driver is controlled by the PWM chopper moder, which effectively avoids losing steps or jittering.
• 【Ultra-quiet Movements】: Featured with StealthChop2, tmc2208 stepper motor driver is an extremely quiet motor driver for two-phase stepper motors, which enables softer and even quieter movements.The continuous drive current is 1.2A and the peak current is 2A, voltage range 4.75V-36V, 256 subdivisions.
• 【UART Mode】:This BTT tmc2208 v3.0 uart mode stepper motor driver comes in UART mode which can be used on control boards by setting jumper caps, no extra wielding requirements, making it flexible to use without redesign or make software or hardware changes.
• 【Terrfic Thermal Performances】:Thanks to the immersional gold finishing, BIGTREETECH tmc 2208 stepper driver generates 30% lower heats compared with TMC2208 of other brands on market. With much better thermal dissipation and cooling performance, it means more heavy duty and longer life of the driver motor.

Potentiometer Setting Instructions: Turn the potentiometer clockwise - reduce Vref to reduce the drive current; Turn the potentiometer counter-clockwise - increase Vref to increase the drive current. If the motherboard provides 12V or 24V, the exact voltage of Vref can be measured. Range of Vref values: default value: 1V (±0.2); MAX: 2V; MIN: 0V; Do not apply excessive force when turning the potentiometer to avoid irreversible damage to the potentiometer. When the potentiometer rotates counterclockwise to its maximum value, it becomes a minimum as it continues to rotate when it is turned clockwise to the minimum. If you continue to rotate, the maximum value is displayed.
