Motor controller, h-bridge circuit.

Hi RC,

I tried both the H-Bridge and ESC's. I prefer the ESC's as in the pic here:

Electronic Speed Controller

The advantage is you only need 1 port on the EZ-B. The H-Brigde is nicely documented in the video's over here. You'll need 5 ports (4 + 1 trigger).

The ESC's might need additional cooling sink in case of heavy loads. They are however internally protected.

I use both ESC's and H-Bridge in combination with these 12V motors with excellent result:

and

12V DC motor with sprocket

Good luck,

Just a small extra remark. You need 1 digital port for each ESC. The H-Bridge does 2 motors at the same time.
