TMC 2208 V3.0 is a newly upgraded driver module. Puts the chip inside, which is more conducive to heat dissipation TMC 2208 V3.0 is an ultra-quiet two-phase stepper motor driver chip that continuously drives in motion 1.4A current, 2A peak current, 4.75 V-36 V voltage range, 256 subdivision. Compared with TMC 2208 V3.0 adopts the high quality flat gold finish,which is more stable,has strong oxidation resistance and better heat dissipation. Flexible microPlyer interpolation unit, the component can provide up to 256 microstep / step resolution, even in the wrist frequency system is limited may still be perfect to achieve sinusoidal control; as stealthChop end music technology is widely used in 3D printing, so that these components are also designed to be compatible with current electronic 3D printer, eliminating the need for expensive redesign. Both components have input pulse / direction, can be completely independent operation. TMC2208 single-axis chip stepper motor drive, power supply tube built-in pilot current 1.4A peak current 2A, voltage range of 4.75V-36V, 256 subdivision; With the patented spreadCycle technology of high frequency chopper, dcStep , stall stallGuard2 , sensing technology, CoolStep dynamic current regulation technology, can save 70% energy.
