Hi all,

I’m also having trouble getting this board up and running. When I connect power all 4 direction and the power led go on. Doesn’t matter whether I2C is connected or not. Any ideas? How to check whether it’s a DOA?

Also, my board has v1.0 printed on the back. Does that mean it’s an outdated version?

And lastly, anyone got stepper motor code for it? That’s what I bought it for but the sample code is only for DC motors.

I’m trying to operate it from an Arduino Uno with several other devices on the I2C bus.

Thanks for any help, Dieter

Ok scrap the all-leds on issue… I was being stupid mixing up 5 and 3.3V VCC…

All help on the other questions still very welcome though!
