I want to make an uninterruptible power supply to work as a backup in case of power outage for BeagleBone Black, which will consume about a maximum of 1A (or slightly more) at 5V. I have a 3.7v lipo battery with protection circuit, a charger , and 1A lipo-to-5v DC booster. I wonder what other parts will I most likely need for this? A diode? P-channel mosfet?
in case of power outage for BeagleBone Black,
Had you not noticed this is an Arduino forum?
Maybe something like this.
Is this a cleaver bit of spam :)
Riva: Maybe something like this.
Yes, probably something like this. I saw it before, but I want to make my own or at least find out a bit how it works.
That A6K part to the left is a pnp transistor? Looks like it doesn't handle much current? So what does it do here?
And what is that part a bit to the right named "KDY3"? And what it's for?
The rest interesting stuff as I see it is a charging IC and a booster.
A6K is a transistor for driving the LED. KDY3 is the LIPO charger chip. You will find all the details and the schematics on the Adafruit site.
