TI Launchpad Powered Off Of Batteries

So it turns out that powering a TI Launchpad off of something other than the USB Power (I dunno, say batteries?)TI Launchpad Powered Off Of Batteries is very very easy. All you need is to get a power supply that can provide anywhere between 1.8 to 3.6Vdc and then hook it up to the VCC(+) and GND(-) pins on a launch pad. So far, I’ve successfully tested this with a set of two AAA batteries (1.6Vdc x2) and also with a single CR2032 battery (3Vdc)

The only issue I can see is the minimum voltage required for some LEDs. For instance, high intensity Blue and White LEDs require a higher minimum voltage of 2.8V to 3.6V (avg 3.2V). Should battery supply voltage drop low enough, certain LEDs may fail to illuminate.

Over all though, it’s Easy Peasy!
