Dual A3697 Stepper Motor Driver Shield

An Arduino compatible stepper motor driver shield. This shield makes use of 2x Allegro A3967 microstepping driver ICs allowing the shield to drive up to two stepper motors independently. The motors can be connected to the shield via screw terminals, or if fitted, via the 4 pin JST connectors. Separate motor power can be supplied via the 2.1mm jack socket or via the shields Vin pin. The shield also includes headers for controlling up to 4 standard servos. An on-board 3.3V/5V logic selection switch provides compatibility with 3.3 and 5V Arduinos.

 


Specification:

Motor supply voltage: 5 to 12V DC
Motor supply current (max): 750mA per motor
Micro step resolution: Full/Half/Quarter/Eighth (set via jumpers) 
Automatic current-decay mode
Fast and slow current decay modes
Internal thermal shutdown circuitry
Dimensions: 69mm x 61mm


Our Notes:

Motor supply voltage (Vin) should be less than or equal to the coil voltage of your stepper motor.
Motor supply voltage (Vin) is directly connected the Vin pin of your Arduino, therefore it should not exceed the maximum supply voltage of the Arduino (normally 12V).
Servo outputs A0 & A1 are not available if motor Y is in use and servo outputs A2 & A3 are not available if motor X is in use.
IIC is only compatible with Arduino Uno.
