    Well from what I heared, the Sequencer should have (just like the Arduino Pro) a voltage regulator that is able to handle up to 12 V (no guarantee). In the schematic it’s marked as “U10” (in Arduino Pro schematic as “U2”). The Atmega328 chip can hadle up to 5.5 V (see Datasheet: http://atmel.com/dyn/resources/prod_documents/8271S.pdf), so a 5V Breakout should be no problem. Maybe the “Bildr Tutorial” will also help you.

    First of all, tanks a lot for your response!
    So the borders are not percentual but as the Datasheet says:
    Charge cut-off Voltage: 4.20±0.03V
    Discharge cut-off Voltage: 2.75 V
    …?
    The whole thing is about an DC-DC step up converter:

    …but i guess that doesn’t include a voltage regulator.
    I’d be happy to hear from you again.
    thanks!

    Hi,
    Can anyone tell me what range the V of the Battery Output has? Is it something like 3,7 V +-5%? I can’t find anything about it… and need it for calculations.
    THANKS!
