Feature:

1. 256 SUBDIVISIONS: Continuing the characteristics of TMC series drivers, the chip is expanded to 256 subdivisions internally, with good mute effect.
2. LARGER CURRENT: The driving current is larger, the maximum peak current is 2.5A, and the stable printing current is 1.7A, stable and reliable.
3. WITH HEAT SINK: The stepper motor driver is equipped with heat sink to ensure good heat dissipation, lower heating efficiency and safe operation.
4. ALUMINUM ALLOY: The heat sink is made of aluminum alloy, with light weight, corrosion resistance, wear resistance and long service life.

Note:

1. Pay special attention to the driving direction, and do not insert it reversely

2. Do not connect the motor when measuring the voltage, otherwise it is easy to burn the motor,

3. When measuring the voltage, connect the power supply, not just USB power supply,

4. When using on the printer control board, please keep 3 jumper caps under the socket.

5. Before adjusting the knob, it must be carried out under the condition of power off. After the adjustment is completed, the power on measurement shall be carried out to prevent the drive or main board from burning out

6. When pasting the heat sink, please pay attention to the distance between the heat sink and the pin, otherwise it will cause a short circuit between the heat sink and the leading angle

7. Under working conditions, please do a good job in heat dissipation (heat sink and cooling fan) to prevent the abnormal operation of the drive overheating
