Two new motor driver shields for Arduino
- 11 December 2014
Thanks for the tip! I'll probably grab some of the compact DRV8835 boards and give those a shot. So far my tests using the Arduino shield with the A-Star did not work, but I'll give it another shot.

Thanks for the reply. I'm wondering if the shield can work with the A-Star 32U4 Micro? I did a quick test today and it didn't seem to work, but since the shield should work with a Leonardo, is there a chance it could work with the A-Star 32U4 Micro?

I'm using the shield to control two of the 120:1 Mini Plastic Gearmotors (Product #: 1516)

They seem to work fine with no extra power added, just using the power provided to the shield from the Arduino, but the product page states that "Attempting to power the shield from the Arduino is not recommended as this could result in large currents flowing through small traces."

How much of a concern would this be for small motors running at low voltage? Should I just flip it around and power the Arduino via the shield by setting the jumper and using the shield's VIN and GND pads?

This looks like a great little board! I just got one and have started experimenting with it. I'm hoping to figure out how to get the Teensyduino libraries to work with it, as there's a lot of good code there to explore.
