● Miniature size 42mmx42mm x21.5mm

● Pulse & direction stepper driver also support the standard RS232 serial command, and built-in 32bit digital chip.

● Using new control algorithms such for vibration suppression and low heat generation

● DC input voltage 12~40VDC, recommended working voltage 24VDC.

● Continuous output current 1.4A max, max peak current 2.1A.

● Integrated design, mounted with 42/39mm stepper motor.

● Low vibration, low noise, stable operation, low motor heating.

● Any micro-step can be set .

● Protection functions such as overvoltage, undervoltage and overcurrent.

● Built-in automatic matching function of motor parameter.

● ADM42H stepper driver can be assembled for NEMA17 Integrated Stepper Motors



Pin No.  Name  Description
1PUPulse Control Signal Input:  5V ~ 24V, Rising Edge effective, 
Make sure pulse signal effective, pulse width ≥ 2μs
Add the resistance for power supply.
2PU-
3DRDirection Signal: high/low level signal： 5V ~ 24V, direction signal should be at least 5 μs earlier than pulse signal,  High/Low level.
4DR-
5EN  Enable Signal：enable/disable.
  If ENA  connect 5V & ENA- connect low level(or Internal optocoupler on), 
stepper controller will turn off the current, motor in free state, no feedback 
even send pulses.  
6EN-
7AMAlarm signal output: When overvoltage, undervoltage, phase loss, or position deviation alarms occur, the alarm signal output is effective;
Maximum driving current 50mA
8AM-
9GNDSupply Voltage Ground: GND/0V
10DC Supply voltage:  12-40VDC, Recommend DC24V

Wire support common anode connection and common cathode connection, controlled by PLC or Pulse Generators.
