DESCRIPTION

TMC2208 single-axis stepper motor drive chip, power tube built-in drive current 1.4A peak current 2A, voltage range 4.75V-36V, 256 subdivision; with patented technology spreadCycle high chopper frequency, dcStep, stallGuard2 stall detection technology, CoolStep current dynamic adjustment technology, can save 70% of the energy, StealthChop mute technology.

Flexible microPlyer interpolation unit, the component can provide up to 256 microstep / step resolution, even in the pulse rate is limited system can still be perfect to achieve sinusoidal control; As stealthChop fine music technology is widely used in 3D printing, so These components are also designed to be compatible with existing 3D printer electronics, eliminating the need for costly redesign. Both components have pulse / direction input, can be completely independent operation. The configuration is implemented via digital input.
