Heat-sink and Thermal Shutdown
The board has current  sense resistors and these resistors has been set as per maximum load current 4.5A, If you use lower current motor, please set the PR1-Preset ( Potentiometer) to the required  level for the motor. At maximum current load TB6600 IC will overheat in some time and a RED LED turns on. This LED goes off once the temperature falls to a safe operating level.

Micro Stepping
A 4way DIP switch is used to set the micro step modes (Full, Half, Eight, Sixteenth), please see the table for Micro step settings. DIP Switch settings should be changed when power is off so the correct selection is active at power up.

Step Pulse
Minimum positive duty cycle of the input step pulse should be 2.2us and required 5V (TTL) signal. A positive going pulse on the step input activates a step operation.

Current Settings
Average drive current can be set using a Preset (On Board PR1 Potentiometer). CN7 (CT) onboard connector   is provided  to measure the voltage to set the motor current (torque). Voltage range to set the torque   0.3V to 3.5V
