Sorry about the lack of data. I guess I need up to 500mA per motor (pager motors draw about 280mA at 3.7 V). About the size, anything that is SMD and can still be soldered by hand. Sorry I am not familiar with all the SMD capsules and sizes. If I knew, I wouldn't have to ask for advice.
I thought people would chip in and say, look I am using this thing for low power motors, perhaps you can use it too.
Thanks for any advice.
