    Hi Enrico, Thanks for your support. I've just change all cables from card to motors
    ad instal electric cables of 6mm instead audio cable of 2,5mm. but the problem not solved. now I want try to change also the cables from psu to card

    Hi Enrico,
    Just yesterday I changed all cables and now I use 6mm

    Hi Gigi,
    As Dimensionengeneering says, a 2.5 cable should be enough.
    I still used 6mm cables …

    "
    Power connections
    As a general rule of thumb, you should use the thickest wire that is practical to make power connections, especially on the battery leads. Using undersized wire will lead to the wire getting hot, and can lead to elevated temperatures on the Sabertooth 2x32 as well.

    The main power connections to the Sabertooth 2x32 are on the rear edge of the board. Connections are made to large black screw terminals. These terminals will accept 10 to 24 gauge wire. Using stranded wire it is possible to run twinned 10 gauge wire connections to the battery terminals. This is often a good idea if your design will be running both motors near or above the 32 amp continuous limit. For the motor connections, single 10 gauge wires should be sufficient for all applications. "

    On the internet I found this which explains the thickness of cables with American system with conversion table.
    What is the AWG measurement system?

    Often when we talk about cables, we hear about this mysterious AWG. What is it and why is it used so often?
    AWG stands for "American wire gauge" and is a standardized system born in 1857 to measure the section / diameter of round conductors.
    The system is particularly widespread in the USA and Canada and stems from the number of leaks used to produce a given wire diameter. A very thin wire (for example 28 AWG) required more passes through the die compared to a 3 AWG wire. In practice this scale derives from the number of passes that the cable must undergo before arriving at the desired section. It is for this reason that as the value increases, the diameter decreases.
    It is very important to consider that this measurement is used only for solid and round conductors, and this is the reason why it is often used in Audio / Video, industrial and electrical cables, because it is a value referred to the single conductor that based on the cable geometry forms the final conductor, with various types of braiding.
    In practice, if we have a cable with a multi-strand braided conductor, when we say that the conductor is 24 AWG, this value does not refer to the whole braid, but to every single strand that makes it up.
    From the American Wire Gauge a conversion table was born with the metric system that generally ranges from 0000 (4/0) up to 44 AWG and covers almost all diameters / sections of conductors used on the market, certainly all those used in the Audio field /Video.
    Below is the conversion table that can be useful to understand the size of the conductor in the metric system.

    Hi Gigi,
    did you solved the problem with the voltage?
