4 Wheel Drive Thumper H Bridge Help

Skip to comments   Jump to end

Well really I want to ask three questions here;

  1. using the 2.5amp dual motor controllers, could I not wire the front and rear of the left and right side of the motors together on the 4wd wild thumper chassis and only use one motor controller?

  2. how would I control the second motor controller, or would I just jump the same control wires from the first one to the second?

3.if I use a 12v rechargeable battery can I directly connect it to the ezb or will it blow? Currently I am using a 7.2 volt RC battery which seems to work fine.

thanks in advance for the help!

ok here is what I did I connected the control lines coming from D15-D18 ezb board together along with the enable line on D19. One h-bridge controller for all 4 motors, no lag and on smoke! So this will free up additional control lines for additional items later. Thanks for all the help in pointing me in the right direction, I was going to do this anyway but wanted input on it. Best of all no script was needed.

Hello,

I have a simple 4wd chasis from sainsmart, using EZB and 2.5 amp Hbrige. I cannot make it to turn (wood floor). The only way I got the platform to run is by stripping out the rubbers on rear wheels so there's less friction and it can turn. It seems that while given the order to turn the Hbridge runs the wheels on both sides at the same speed while the wheels on the inner side should run much slower than the wheels on the outer side, is that correct ? If so, do you know what could possibly allow me to have the wheels to turn slower on one side beside using PWN each time I want to turn ?

Thanks,

Elfege
