Is a dedicated power supply required if I use the Shield?

Hi, do I require a dedicated power supply for SparqEE Cell if I connect it via SparqEE Shield with a Raspberry Pi 2?

The default setup is yes, it and the RasPi require their own power supplies.

You can either use a two cables, a 'Y' connector, or even jumper the 5V power pin to the CELLv1.0 to power it.

You could directly power it from a shield but you would need to create your own shield or jumper it yourself.

Thanks for your response. It helps. But I still don't clearly know what is best for my situation.
I would appreciate if you could clarify the last bits.

I am new to Raspberry and ARM world.
I would like to run it behind a UPS (with rechargeable batteries).

So, you were so kind to outline the following options:

From power source directly via:
- two cables
- Y connector

Here I know what to do.

From RasPi directly:
- jumper 5V power pin to CELLv1.0



Do I understand you correctly that I can use a cable from the two 5V pins to the CELLv1.0 to power it?

Which option do you recommend for my situation?

It's easiest always not to have to do anything custom... just get a Y micro cable off of amazon if you only want to use one type A usb adapter. If you want even easier, just use two normal type A to micro connectors. You could also jumper that 5v pin to the Vin of the CELLv1.0 and bypass the USB pins.
