TMC2208 Stepper Motor Driver V1.2 - 5 Pack with Heat Sink for 3D Printers - Compatible with Ramps 1.4, MKS Gen, Mega i3, Ender-3 Pro - Silent Step Stick for Smooth Printing Operations

TMC2208 ste ppen motor driver adopts stealthChop2 Mute technoloey which reduces motor noise to the point of silence at low ve lecities to ensunes noisele ss ope ration.The sound when printing around 55d8.You will mot feel noisy and anoyed when you are sleeping.In the complex interference environment, the signal is still stably transmltted and has good compatlbilltyComparing to other stepper driver through the test，TMC2208 silent stepper driver generate lower heat also it has a large-area cooling position to lower the temperature when drive is working.TMC2208 driver needs extra fan to cool it, otherwise the high temperature may destroy it.Do not connect the motor when measuring the voltage, otherwise it is easy to burn the driver.Power should be connected, do not just connect USB power supply. Interface: Step/DirConfiguration: CFG Pins or UARTNative Microsteps: up to 1/256 MicroPlyer Microsteps: 1/256Logic Voltage (VIO): 3-5VMotor Voltage (VM): 4.75-36V Motor Phase Current max: 1.2A RMS, 2.0A Peak.Reference voltage：≤1V.
