    hi all!

    I change the H-bridge to IBT-2 because have more option to the future change to 24v motors and the current is bigger (43A) x Monster that have 20A nominal.

    Finish the wiring and make test and adjust on PID. Everthing work fine. I use the code of "Sirnoname" XPID, and work very well!

    I make the joint with 3d printer, bolt's and universal end joint.

    hey! great work.
    i really like how simple and small everything is build.

    what´s your experience with the motor mounts? are they stealth?
    do you use steel or aluminium as plate material?

    thanks for your help!

    greets

    Hi Dieser,

    Dear All!

    I can do work everythings without burn notting! After study alot time, I can find the cause of burn my H-bridge IBT-2!

    I use the firmware X-Pid with arduino, and after many measurements I check that the frequency of PWM to control the h-bridge work around 30khz, but IBT-2 work just with 15khz.

    I Buy this one dual H-Bridge on aliexpress:

    This Board work with 60khz and everything work cold and fine!
