Overview:
-
Simple step and direction control interface
-
Six different step resolutions: Full step, half step, 1/4 step, 1/8 step, 1/16 step and 1/32 step
-
Adjustable current control (potentiometer on the board) allows the maximum current to be set
-
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
-
45 V maximum supply voltage
-
Built-in regulator (no external logic power supply required)
-
Can be connected directly to 3.3 V and 5 V systems
-
Thermal shutdown in case of overtemperature, shutdown in case of overcurrent and shutdown in case of undervoltage
-
4-layer, 2 oz copper PCB for improved heat dissipation
-
Exposed solderable ground pad under the driver IC on the underside of the PCB
-
Module size, pinout and interface match those of typical A4988 stepper motor driver carriers in most respects
