3.1 Connector P1 Configurations

Pin Function
V+
GND
VCC
DIR
STP
ENA
Note:
(1) Input is considered high level if this terminal is not connected.
(2) Low-level pulse duration should > 4μs.
(3) An active low-level input shuts down power supply to the motor. High-level input or left open
makes the controller fully working. When awaken from shutdown mode, wait 1 millisecond
before sending pulse.

3.2 Connector P2 Configurations

Pin Function
A+/A-
B-/B+
Warning: Incorrect connection of phase winds will permanently damage the driver.
Resistance between leads of different phases is usually > 100KΩ. Resistance between
leads of the same phase is usually < 100Ω.
Warning: In addition to the port of power supply and motor, the voltage of rest port
must be in the range of -0. 3V ~ 5. 3V, otherwise it will permanently damage the
controller.

4. Typical application

ISD02/04/08 driver's wiring is very straightforward as shown in following Figure. Terminal 6 (EN) can be left
open if offline is not needed.
