There is really not a lot to say about such a simple device, other than to state how easy will it be to drive your two DC motors on that small mobile
robot. Don’t be confused, though. Just because the board measures 1.1” by 1.1” does not mean there is not a lot of power within.
The left side connector will give you access to power and all the control signals. SMT pads allow you to solder either a 100 mils pitch header connector or
your own wires. Is up to you! Same applies with the right side connector, where the four power outputs are made available.
All you need to do is provide a VM voltage, ranging from 2.5V to 10.8V, and four control signals to control both H Bridges. These are AIN1, AIN2, BIN1 and
BIN2. You can either PWM these signals to control both speed and direction, or just use HI/LO combinations to enable/disable and control the direction on either motor.
Do note you will get an astounding 1A RMS, 2A peak, per H Bridge. That’s a lot of juice for such a small device!
So you see? That’s pretty much it! The question now is: what cool project will you develop with it? Let us know and do not forget to stay tuned to
our blog as we will detail cool implementations such as:
- Stepper Driving
- Paralleling H Bridges for twice the current
- Class D PWM modulation
