Newbie question here, I am wondering which lilyPad board and battery would I need to run around 40 micro LEDs, in strings of 10. The LEDs would not do anything too fancy, just blink, or strobe. I had originally thought of going with the main board and some AAA batteries, but the ran across the lilyPad Simple with the built in JST connector for a LiPo battery.

Is a lilyPad Simple enough to power 40 LEDs in strings of 10?

For the battery, If each LED consumes around 20mA, and I have 40 of them, then I do I need a LiPo with at least 800mA output?
