Hi robotmaker,

I would like to use the EZ-B to control the Ultimate Wall-e, but using its H-bridge. On the attached pic it looks like the H-bridge has 8 mosfets???

Would it be possible to even use the EZ-B with this type of H-bridge? It looks like each motor has 5 wires, yellow grey grey + red black, green grey grey + red black ?

I found this circuit diagram on the web that is supposed to drive two motors & may be similar to above config?

Please advise if you have the time.

Thank you,

yes can work with 4 digital lines,not really that great,they not using mosfets,there are simple circuit to add to it to make a 2 wire bridge mosfet bridge would work better,they only using it likes 4 wires,rest is a tach or speed switch
