Features: TMC2208 is quiet two-phase stepper motor driver chip, with a continuous driving current of 1.4A, a peakness current of 2A, voltages ranges of 4.75V-36V, and 256 subdivisions; Equipped with patented technologies such as spreadCycle (high dynamic chopper) stealthShop2 (quiet technology) and microPlyert (subdivision control). The flexible microplyer interpolation unit can provide up to 256 subdivisions, allowing for perfect control even in systems with limited pulse frequencies; Due to the widespread application of stealthShop2 quiet technology in 3D printing, the design of these components is also compatible for existing 3D printer electronic devices, eliminating the expensive cost of redesign. It have a standard step/dir interfaces, making it easy and convenient to use. Ideal for electronics enthusiasts, robotics engineers, and maker upgrading DIY projects like 3D printers or automateds tools requiring quiet, high precise motor control.
