Features
Support wide voltage range input (DC 24V~80V)
Support 16 steps and subdivision settings, the resolution can reach 40,000 pulses/revolution
Support 16 gear drive current settings, adjustable from 0.5A/phase to 5.0A/phase
Support three control methods:common cathode, common anode, and differential
Support undervoltage, overvoltage, overheat, overcurrent alarm
Support power-down phase memory function
Both I/O signal and input signal are optically isolated
When the step pulse stops for more than 100ms, the coil current is automatically reduced to half of the set current
Provide complete supporting information manual (provide Raspberry Pi, STM32, Arduin0 example)

PU+/PU-:Pulse signal control, a pulse motor takes one step, and the pulse width must be >2.5us;
DR+/DR-:direction signal control;
MF+/MF-:It is the motor enable signal control;
There are three wiring methods:common cathode, common anode, and differential
Common cathode:PU-, DR-, MF- are grounded, PU+, DR+, MF+ are connected to control pins, high level is effective
Common anode:PU+, DR+, MF+ are connected to 5~24V, PU-, DR-, MF- are connected to control pins, low level is active
Difference:It can be combined in two ways:common cathode and common anode;
Note:It is recommended that users use common cathode connection when using
Package includes
1 x Motor driver
