TMC2208 Stepper Drivers
- 【Ultra-quiet Movements】: TMC2208 is an extremely quiet motor driver for two-phase stepper motors.The continuous drive current is 1.2A and the peak current is 2A, voltage range 4.75V-36V, 256 subdivisions.Stealthchop ensures the motor's noiseless movements.
- 【Smooth Operation】:Incorporated the Spreadcycle technology, The TMC2208 is controlled by the PWM chopper moder, which makes the motor operate more smoothly, and effectively avoids losing steps or jittering.
- 【Terrfic Thermal Performances】:Thanks to the immersional gold finishing, The TMC2208 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.
- 【UART Mode】:TMC2208 can be used also in UART mode where the stepper motor setting and tuning can be done through simple serial UART interface with your micro-controller,which make it flexible to use with any 3d printing board without redesign or make software or hardware changes.
