Hi,

I need to control a 16 haptic motors and I'm using a 3.3v feather board. Can I just hook them into the digital out pins?
On the haptic motor tech details, it says that at 3v, the motors pull 60ma, which matches what the feather should output. I was thinking of putting a current limiting resistor to make sure that there are no surges above 60ma, and a flyback diode to protect the pins. Can I get feasability feedback? I'm trying to avoid wiring a bunch of transistors.

THANKS!
