Panda II voltage source


#1

Panda I is rated at 7V to 12V
Panda II is rated at 6V to 9V.

It’s the sames voltage regulator, so why is it not the same voltage?

We use a 12V battery and a panda I, but we need to upgrade to a panda II.


#2

12V will be fine on both boards as long as you do not add more circuitry that draws more power, which will cause the regulators to over heat.


#3

From my own experience, don’t try for an example to stack a Fez connect shield on your panda using more than 7,5 VDC, it can heat very quickly ! If you want to use a higher voltage power supply, just use a small DC/DC converter that will convert your power without dissipating it into heat :slight_smile: You will save your batteries life too !


#4

I have a 12V to 5V regulator, will the panda work with 5V?


#5

If you got regulated 5V then you can connected directly to 5 volt pin (not Vin)
