BigTreeTech TMC2209 V1.2 Stepper Motor Driver With Stallguard functionality, these 2209s provide a load and loss of speed detection technology Coolstep provides a current dynamic regulation technology that saves up to 75% of electrical energy. Ultra-quiet two-phase stepper motor driver chip, with a continuous drive current of 2A, a peak current of 2.8A, a voltage range of 5.5V-28V, and 256 subdivisions. The motor controlled by the PWM chopper mode operates more smoothly and without jitter. The flexible microPlyer interpolation unit provides up to 256 subdivisions, which can achieve perfect sinusoidal control even in systems with limited pulse frequency; this is also because the StealthChop ultra-quiet technology is widely used in 3D printing. Compatible with existing 3D printer electronics, eliminating the expensive cost of redesign.
