Onboard regulator is rated at 800mA with proper heatsink.
Will cut off sooner if gets too hot.
If you'd ordered from dipmicro on the 6th you'd have had it already ...
I am sure I have one in the box down stairs, just need to go look
Any chance you run to YouDoIt Electronics in Needham & grab one?
Or maybe poke around Ocean State Job Lot?
I have yet to go to You-Do-It, but I have it on my list next time I have free time and am in Needham
As for Ocean State, I got that covered... The wife works for them.
