Hi,

For Hbridge motor shield, does it have the protection to the reverse current of the motors so it won't damage the broad?

Also, can I control 4 DC motors by using 2 Hbridge motor shields?

Thank you

The A4988 controller on the shield takes care of the motor protection, and will shut down until the situation abides. However the shield isn't stackable unless you physically modify one of them to use different digital pins.
