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. This should be a 6V to 30V, 2A or more power supply that is clean low ripple. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.

Ce site contient essentiellement des notes de travail. This normally high input signal will minimize power consumption by disabling internal circuitry and the output drivers when pulled low. Each rising edge of this signal will cause one step or microstep to be taken. The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. These digital inputs control the microstepping mode.


This one is complicated – please see the datasheet for more information. They are all connected together inside the board. See below diagrams for how to hook these up.

This needs to be a 0V to 5V or 0V to 3. The tabs are at ground potential and need no insulation. There are no news items available for this product. Affichages Lire Voir le texte source Historique.

Allegro MicroSystems – A Microstepping Driver with Translator

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. Espaces de noms Page Discussion. Menu de navigation Outils personnels Se connecter.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection. 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.


Electronique/Hardware/Moteurs/Allegro A3967 – EasyDriver

This normally high input signal will reset the internal translator and disable all output drivers when pulled low. We default it to slow decay mode, but you can override with your own voltage on this pin. The translator is the key to the easy implementation of the ASLB. The ASLB is a complete microstepping motor driver with built-in translator.

There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program. Connect this to the positive power supply lead. Click the image to view larger. Special power-up sequencing is not required.

This is the power input to the Easy Driver.
