While dealing with robotics, there may be some cases where L293D isn't quite a good option due to its current limitation. In those cases, we opt for more powerful drivers. Let's have a look at another product from robokits, which can pretty much drive powerful high torque motors:
Dual motor driver high power. Picture source: http://robokits.co.in/motor-drives/dual-dc-motor-driver-20a
The preceding motor driver is my personal favorite. It has multiple controls and can drive high torque motors. The driver has the following five control pins:
- Gnd: Ground.
- DIR: When low, the motor rotates in one direction; when high, it rotates in another direction.
- PWM: Pulse width modulation to control the speed of the motor. Recommended frequency range is 20 Hz - 400 Hz.
- BRK: When high, it halts the motor in operation.
- 5V: Regulated 5V output from the motor driver board.
