Pin Assignment and Description

Signal	Function	Description
PLS+	+ input Opto-isolated positive	Connect +5V power supply, work with +5V - +24V, limited resistor needed when higher than +5V.
PLS-	-  Pulse signal	Effects with falling edge, motor runs one step when input pulse change from low to high, input resistance is 220Ω, low level 0-0.5V, high level 4-5V, pulse width>2.5μs.
DIR+	+ input Opto-isolated positive	Connect +5V power supply, work with +5V - +24V, limited resistor needed when higher than +5V.
DIR-	- Direction signal	Used to change motor running direction, input resistance is 220Ω, low level 0-0.5V, high level 4-5V, pulse width>2.5μs.
ENA+	+ input Opto-isolated positive	Connect +5V power supply, work with +5V - +24V, limited resistor needed when higher than +5V.
ENA-	- Motor release signal	Low level, motor coil current cut off, driver stops work, and motor is not locked.
