    I found this Motomonster http://articulo.mercadolibre.com.ar...r-motores-de-dc-30a-arduino-raspberry-arm-_JM

    Moto Monster Driver is able to control a DC motor up to 30A . Uses a bridge -H VNH2SP30 ST Microelectronics .
    When used in high-current applications , greater than 14A , it is necessary to improve the thermal resistance with a heat sink or fan and solder wires directly to the board instead of using a screw terminal . However, when this shield used with currents up to 6A chips barely noticeable warm.


    Features


    Highest voltage : 16V
    Maximum current: 30A
    Recommended without sink current : 14A
    Sensing current through an analog pin of Arduino
    MOSFET ON Resistance : 19 mOhm
    Maximum PWM frequency 20 kHz
    Shutdown temperature
    Off for low and high tension
    Protection against cross conduction

    This is the first time I see it, I was looking for the tipical motomonster, but if I'm not wrong, it is better to get two of these than one of the originals, isn't it?
    Would be the same to connect to Arduino?

    hi this driver is a single motor driver and works like the well known h-bridge. IMO it is not worth the money due to the low cost of the MM h-bridges from aliexpress. Keep in mind that the h-bridges can be used as a "2 in 1" single driver to raise the needed current. More information you will find in the FAQ.

    Thank you for your reply!. Yes, I already read the faq, my problem is that I can't order outside my country and here the MM clone cost about 60% more than this little fella.
    Anyway, I will buy a MM and arduino just to play with them until my JRKs arrives in June, and maybe in the meantime I can get the Ard+moto to work! who knows! :p
