PLEASE HELP - Did I break my arduino/PoEthernet Shield??

Hello everyone, I would appreciate any help as I feel I screwed up either one of my favorite new toys(Arduino Uno or PoEthernet Shield)

I’m sorry for the super long post but I wanna be as desrciptive as possible as I want to see if i can get my setupd to work withough having to buy a new arduino or shield because im low on funds :expressionless:

I’ve had my Arduino for some time now, it was my 3rd microcontroler so I’m not a complete noob in this sense

I’d built many different test circuits with success.

Anyway recently I bought myself the PoEthernet shield because I’ve always wanted to get my arduino online but honestly I’ve never used a shield before so I’ve been a little lost when it came to buying headers etc.

So anyway I bought myself these break away straight headers:

If I’m not mistaken the shield only uses pins 10,11,12,13 and 4 so I soldered headers ONLY to those pins. Plus two more single headers at the opposite side of the shield(1 at 3.3V and 1 at Analog In 5) just so that that side of the shield would also be sitting on headers.

Anyway so I stacked it on top of my arduino and plugged my arduino to my comp with the USB cable and I saw the usual LEDs on the Arduino light up and also some LEDs on the shield lit up(dont remember which ones exactly, I just remember seeing LEDs going on and off)

My computer said something about a new device that was not recognized I believe(Sorry it was last week I cant remember the exact message). Ive never gotten this message in the past when plugging in my Arduino by itself so I knew it had to do with the shield. I tried plugging and unplugging the USB a couple times with the same result so I decided to just remove the shield till I had done more research about the code I need to upload to the Arduino etc,

Anyway today I was ready to try again but now when I stack the shield and plug my arduino to power through USB or through power adapter, I only see the Arduino light up and not any lights on the shield. Idk if my setup with the headers messed something up or I’m missing something here. The shield just looks completely dead, no LEDs at all light up.

The only other thing I’ve done with my arduino since last week when I first stacked the shield into it was mess with some relay module I have here. I wasnt too sure about how to wire that up either because thats something I’ve never done but I finally got it to work. I was using pin 12 to trigger a transistor which then triggered the relay

I thought maybe while messing with the relay I screwed something up on my arduino but I doubt it because the relay board seems to have protective diods, also there was no load on the relay i was just trying to see if I could trigger it, and plus I tested pins 10 through 13 and they seem to be working just fine

ANY help/suggestions would be appreciated :shifty:

Here are some pics of the shield and arduino

According to the schematic of the PoEthernet shield, you need to add header pins to GND, +5 and RST.

Really?? How did you determine that?

I’m looking at this:

I’m not very familiar with reading schematics yet so can you explain where it says about those 3 pins/headers PLease.

Thank you. And im at work right now but I will try adding those headers as SOON as I get home, I hope this solves the problem

P.S. thanks for your prompt reply i appreciate it

The symbol in the lower center, ARDUINO_SHIELDNOLABELS represents the connetions between the shield and Arduino, so you see which pins are connected to anything. Looking at the rest of the schematic tells me that Vin only goes to connector JP1, D2 to the interrupt pin of the Wiznet chip if you jumper across SJ2, and D3 looks like it’s not used.

3.3v isn’t used (likely to avoid overloading the regulator on the Arduino); the board makes its own 3.3v from 5v using IC2.

THANK YOU VERY MUCH MIKE!

I added those 3 headers(and removed the 3.3V) and now I get a blue Power indicator on the shield :dance:

Ok NOW I can start typing away and figure out how to program it. Thanks a lot again
