Connect the negative side of your power supply, as well as from any other boards you are using to drive the Easy Driver to one or more of the GND pins.

Special power-up sequencing is not required. These digital inputs control the microstepping mode.

This normally high input signal will reset the internal translator and disable all output drivers when pulled low. The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes.


This needs to be a 0V to 5V or 0V to 3. By simply inputting one pulse on the STEP input the motor will take one step full, half, quarter, or eighth depending on two logic inputs. This normally high input signal will minimize power consumption by disabling internal circuitry and the output drivers when pulled low.

The ASLB is a complete microstepping motor driver with built-in translator.

The tabs are at ground potential and need no insulation. There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program.

This one is complicated – please see the datasheet for more information. They 39677 all connected together inside the board. Ce site contient essentiellement des notes de travail. We’ll notify you when there are updates to this product. The translator is the key to the easy implementation of the ASLB. This is the power input to the Easy Driver.

A and B are the two coils of the motor, and can swap the two wires for a given coil it will just reverse the direction of the motor. Affichages Lire Voir le texte source Historique.

Connect this to the positive power supply lead. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. Menu de navigation Outils personnels Se connecter.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection. This should be a 6V to 30V, 2A or more power supply that is clean low ripple.

Each rising edge of this signal will cause one step or microstep to allegr taken. We default it to slow decay mode, but you can override with your own voltage on this pin.
