  • I'm afraid I don't - I think for pretty much any motor you'll need an or FET/transistor to turn it on based on the GPIO. However the CR2032 batteries really aren't designed to provide that amount of power, so even if you do get it working it'll reduce battery life quite a bit.

    Having said that you can get LiPo CR2032s, and while you can't use them directly because of the increased voltage, the Pucks actually have an area where you can cut a wire trace and solder on a diode, which will drop the battery voltage by enough to use it.
