My ShieldBuddy has an Ethernet Shield. I have been testing powering the board with different voltages. Here are my findings:

1) 12V to DC Jack - Did not even try it. Please see 2) below.

2) 9V to DC Jack. Works but board get too hot.

3) 7.5V to DC Jack. I found this to be optimal. Supplying enough voltage and board does not get hot.

My question is:

Can I use a 5V (2 Amps) at Vin? I prefer this approach to powering via the DC jack with 7.5V. I cannot easily supply 7.5V to Vin due to my configuration.

Thanks in advance for the community's help.

Move the jumper to the VDC position first.

I moved the jumper so that I can use the external jack but just wanted to check that using 5V(2Amp) will be sufficient to also power the shield?
