Massduino UNO LC is an Arduino compatible board, It’s based on Arduino UNO R3 design, So you can use MassDuino UNO LC as Arduino UNO, All Code, shield and IDE for Arduino UNO R3 are also valid on MassDuino UNO LC, Some visible improvement on hardware make MassDuino more flexible and easier use , For example: 3.3V or 5V IO selectable allow you connect some 3.3V modules (such as XBee) to Massduino directly.

The 5V Current limit is depended on the voltage difference between input and output , the regulator power consumption can be calculated below:
Pcm = (Vin - Vout) * Icm
In MassDuino UNO LC’s design , the Pcm must limit within 3.5W , so if the Input voltage is 9V , the voltage difference is 9V-5V = 4V ,to limit Pcm within 3.5W ,the current consumption must limit within 3.5V/4V = 0.875A.
The 3.3V max current consumption must limit within 600mA.
Again , the 3.3V LDO is serial to 5V regulator, to calculated 5V power consumption , must consider the 3.3V current consumption.
