• The TMC2209 is plug-and-play, ultra silent, micro step subdivision: up to 1/256 micro steps. Equipped with large heat sinks for good heat dissipation
• Support UART/STEP/DIR Mode, Supports sensorless feedback function
• Current adjustable: set motor current through potentiometer to adapt to different motors
• The motor controlled by the PWM chopper mode operated more smoothly and without jitter
• Applications: 3D printers, CNC engraving machines and diy robot
