4A 4 Channel Driver Motor Shield ComMotion Robot Controller KR03058
The ComMotion Robot Controller is an IC controlled, 4 channel motor controller in an R3 shield format. The advantage of using IC controlled shield is that it only uses 2 pins. This leaves most of your pins free for use with other shields, sensors and circuits. The ComMotion shield can drive 4 DC brushed motors up to 4A per motor. Current monitoring is used to limit the maximum current for each motor. Each motor has an encoder input that can be used for precise speed control. Encoder feedback also gives the motor much more torque at lowspeeds.
