Overview

Massduino LC is an Arduin compatible board, It’s based on Arduin UNO R3 design, So you can use MassDuino LC as Arduin UNO, All Code, shield and IDE for Arduin UNO R3 are also valid on MassDuino 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.

Notice

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.

All of the PCBAs have passed 130 items testing by 100% automatic, 100% quality guarantee.
