"Nima and Syvwlch have both mentioned that they've used the TLC5940 to drive small 3V DC motors."
- I used 1.5 V pager motors @ 70 mA..... Plus, I never had more than 4 on at a time, although I had 16 connected......
I dont know if this makes much difference, but I was using a different TLC5940 library at the time too.
