Simple test:
1. Set up a meter to measure the voltage at CN2 +5 to GND.
2. Turn power on to the until, observe the red led on the bottom go out - Did the voltage drop below 4.5 volt?
3. Press the On switch (Next to the 24 pin connector) the red LED should light up
4. Watch the voltage, it should start above 5 volts and not drop more than 20% (4V) NOTE: This is a guess since this product is closed there is no means to tell how they derive the voltages needed - since the Atom chip is a 1.8 volt device this assumes voltage regulators that provide 3.3, 1.8, 1.2 volts and don't forget the Atmel device that requires 4.5 volts to function at 16mhz.
