Umesh,

We're on the East Coast, and it looks like you called after hours. :)   No problem...Your package is on it's way (shipped Saturday), and I'll give you a call later today.

That is fine for the serializer itself. It only draws 100mA or so. The only thing to watch out for is if you start adding alot of peripherals. Motors, sensors etc, that could add up to more than 3A. Motors would be the major thing to be wary of.
