Driver interface and wiring diagram

PULPulse control signal: effective pulse falling edge,
pulse voltage of 5V, maximum frequency of 1MHz.
DIRDirection control signal: High and low level pulse signals,
high level of 5V.
VCCCommon port
ENEnable control signal: When effective(high level 5V),
motor is free. It is used for motor debugging.
GNDPower supply
A+Motor phase A
B+Motor phase B
Current setting

The peak current output is set through SW1, SW2, SW3 dial switches

Half current locking

Automatic idle current reduction to reduce heat after the motor stops moving for 0.1 seconds if SW4 is set “off”.

Subdivision setting

The subdivision value is set through SW5, SW6, SW7, and SW8 dial switches, and a total of 16 subdivision settings are optional.
