Description: TMC2208 single-axis stepping motor driver chip, power tube built-in drive current 1.4A peak current 2A, voltage range 4.75V-36V, 256 subdivision. microPlyer interpolation unit, this component can provide up to 256 microsteps / step resolution, even in systems with limited rate can still achieve perfect sine wave control. Because stealthChop fine music technology is widely used in 3D printing, these components are also designed to be compatible with existing 3D printer electronics without the need for expensive redesign. Both components have /direction inputs and can operate completely independently. Configuration is achieved through digital input. Specification: Material: 4 layers PCB board Size: 20*15*20mm Scope of application: 3d printer Package Includes: 5Pcs TMC2208 V1.0 Driver 5Pcs heat sink 1Pcs screwdriver Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
