Pololu社 12A、5.5 - 24V シングルモータコントローラ

We use these for the 4 person team Skills Ontario Robotics competition for the last 2 years to control all parts of our robots they work awesome!

Super-prompt service and a fair price from Robotshop. Robust and well documented. Doesn't break a sweat running at 4.7A 19V. Nice that they include the connection terminals. One strange quirk: The current sense output is a bit asymmetric and there is a small deadband around zero -- so positive and negative currents require different zero offset calibration constants.

They motor controllers are very easy to interface with and are very reliable. We were using them for two motor that drew 8A continuous and 13A peak for short durations. These controllers did not heat up or get damaged.
