BTT TMC2209 V1.2 Stepper Motor Driver

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.
