Dearthanks for you response, I'm reading some documents, for example:https://learn.sparkfun.com/tutorials/using-the-arduino-pro-mini-33vhttp://www.dominicdube.com/wp-content/uploads/ProMiniPinout.pngBut Read doesn't mean "understand" for me.Best regards.
I think if you measure between the two pins, you will find the VCC pins are connected to each other.So, Yes to your question.
If you have a high voltage battery then yes, connect it it raw.
But a Pro Mini will just work fine on a 4,8V LipPo or something and you want to connect it to Vcc (even a 3,3V Pro Mini, this will only still run @ 8Mhz). The 5V is no must.
When is a high voltage battery not a high voltage battery? When it is fully discharged (!)
A battery is a variable voltage, unregulated, power supply.
There is no such thing as a 4.8V LiPo.
I would think powering a digital circuit directly from a LiPo, without some form of regulation and conditioning, a very poor design.
However, the documentation is very clear; see the paragraph titled power.
So. Whilst you could hook a LiPo directly to VCC and it may work, apparently 'just fine.' It is not what you should do.
It [a battery, is] unregulated, yes. But it's very very clean Nothing wrong with connection it to a uC. Like every remote etc in your house will it this way.
Yeay yeay, it was just an example.
But still, the 4,2V of a LiPo is perfectly fine to drive the Pro Mini direct to Vcc.
The 8Mhz (also called 3,3V) version will run within spec to as low as 2,25V so the whol LiPo range.
Yep, but your interpretation is not
