5pcs TMC2208 V1.2 Stepper Motor Driver Module with Heat Sink Screwdriver for 3D Printer Features: TMC2208 is an ultra-quiet two-phase stepper motor driver chip with continuous drive current of 1.2A, peak current of 2A, voltage range of 4.75-36V, 256 subdivision. The flexible microplyer interpolation unit provides up to 256 subdivisions, perfect for sinusoidal control even in systems with limited pulse frequency. Since the stealthChop2 ultra-quiet technology is widely used in 3D printing, the design of these components is also compatible with existing 3D printer electronics, eliminating the costly cost of redesign. With a standard step / dir interface, it is simple and convenient e. Configuration is achieved through digital input. The TMC2208 driver module can replace the TMC2100, A4988, DRV8825, LV8729.
