Description: This kit is the same product as the Ardumoto Shield but it also includes headers and screw terminals. The board and parts come in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap.

This is a motor shield for Arduino that will control two DC motors. Based on the L298 H-bridge, the Ardumoto can drive up to 2 amps per channel. The board takes its power from the same Vin line as the Arduino board,  includes blue and yellow LEDs to indicate active direction, and all driver lines are diode protected from back EMF.

Control for motor attached to OUT1/2 is connected to digital line 12 (direction A) and digital line 3 (PWM A). Control for motor attached to OUT3/4 is connected to digital line 13 (direction B) and digital line 11 (PWM B).

  • The schematic link is broken

  • can i use it to drive the tamiya gearbox?
    and, can i use a voltage lower than arduino Vin?

  • I used one of these to drive an antenna rotor motor at 24V, and it worked great. I had to modify the board so that the LEDs were disabled and the Vin trace from the terminal blocks didn’t go to the Vin pin of the Arduino. The chip on this board is identical to the one on the official Arduino R3 shield, but this one doesn’t have braking control. I don’t miss the current sense, but having braking control would be very nice. I know why it isn’t on the board – it saves two digital pins. Maybe a solder jumper to enable/disable the feature, like on the R3 board?

    Nice board, some very minor feature additions would be nice.

  • Can I connect more then 1 shield to Arduino?

  • I made a video of myself making this product and have posted it on YouTube you can find the video at https://www.youtube.com/watch?v=rGcYL2yuseA

  • Is it common that this shield doesn’t fit around the USB and DC adapter ports on the Arduino Uno? …rather annoying considering that the device is built specifically for the Arduino. Regardless, the bigger problem is that only one of the two pairs of output pins (to the motor) appears to be working. This is the case with both of the shields that I purchased. Any advice, anyone?

  • Sparkfun should sell official arduino ones

  • does it support the ROB-10846 Motor on this shield?

  • Please fix the schematic link

  • Heloo all
    I have a question, maybe some none could help me iv bought this Ardumoto and an other shield, the Joystick Shield
    http://www.sparkfun.com/products/9895 , this one but not the retail version.
    My question is:
    Can use them both at once on my Duemilanove??

  • okay i am a littel confused here.
    i have the ardumoto bord sitting on top of my Arduino uno and to 12v motors on the 1, 2 and the 3 ,4 pin. The hole thing get its power from a 12v 2amp supply that is conectet to the Arduino
    i can massure 11.94v on the + and - pin on the ardumoto bord but i can only massure 8.67v on the motor out pin (1, 2 and 3, 4 pin) when the pwm pins gets the full 255 anlog out from the Arduino. Isent it supposed to supply the motors the full 12v ( or my 11.94V) when its is going at full speed?
    thanks in advance.

  • How would you go about revising the example Arduino sketch to allow it to be controlled by the serial port. I want to eventully be able to pop an Xbee shield on and run without the USB cable.
    Thanks
