Product Features:

• Tags:3D printer accessories, TMC2209, stepper motor driver module, 256 subdivisions, PCB mount
• High quality, super quiet;
• The working temperature is high. Without a fan, the operating temperature is about 70 degrees at 0.5A and over 150 degrees at 1A, which can cause out of step. It is recommended to do a good job of heat dissipation, and the best working current is 0.5A;
• Algorithm and adjustment of TMC 2100 module drive current ---- and attention!
• Drive current algorithm: i = vref * 1.9 / 2.5, the default Verf is about 0.65V, so the default current is 0.5A, and the maximum current is 1A;
•   Verf measures the voltage between Gnd and the potentiometer;
• When measuring the voltage, do not connect the motor, otherwise it is easy to burn the driver;
• Please also connect the power supply when measuring the voltage, don't just connect the USB power supply;
• Please pay special attention to the direction, do not insert by mistake;
• High-quality original factory shipment, 30 days worry-free return and exchange;
