The Ardumoto shield is a great shield for beginners to robotics and mechatronics. It is designed to perfectly fit on the Arduino Uno or Mega pins.
The shield features a L298 H-Bridge dual-motor driver. This means it can drive either:
- 2x DC motors, or
- 1x 4 Phase Stepper Motor.
The Ardumoto comes unsoldered with stacking headers included (in case you want to solder it directly to wires).
