ALLIANDISTMC2209 V2.0 3D Printer Stepper Motor Driver Ultra Quiet with Heatsink Endless Tip Zero Return 2 Pack

TMC2209: has all functions of tmc2208 and can completely replace tmc2208. At the same time, tmc2209 has better heat dissipation, supports larger currents, and supports sensorless functionality.Features: Support sensorless feedback function. Support uart mode by installing jumpers instead of soldering on mks gen_1 V2.0, skr1.3/1.4 and mks sgen_1.[Mute & Low Power Consumption]This module allows for quiet and high-precision hash algorithms for silent motor movement and silent shutdown, making it super quiet during the printing process. With an RDSon value of 0.2A, the TMC2209 driver has an output driver with a lower resistance line, which provides lower power consumption and higher current.[Precautions] The voltage of Gnd and potentiometer measures the voltage of Gnd and potentiometer. Please do not connect the motor when measuring voltage, otherwise it is easy to burn the driver. When measuring voltage, please connect a power source, not just a USB power source. Please pay attention to the direction and do not accidentally introduce itHigher drive voltage: the drive current is larger, the maximum peak current up to 2.5A, stable pressure current up to 1.8A. Support Modes: Support UART mode, perfect for use with MKSSGEN-L, no jumper needed.
