Wave Shield not showing up in ports

by AngryIcelandicShouting on Thu Aug 13, 2020 2:45 pm

Hi, I just finished soldering a Wave shield and am eager to use it, but when I attach it to my Metro 328 board (which is working fine and recognized in the ports section of the device manager), the computer stops recognizing the board and shield. I am thinking I might have shorted something so here are some photos to verify:

Thanks in advance!

I don't see any obvious short circuits, but the ip-amp (IC3) appears to be installed backwards. The dimple indicating pin 1 should be on the end closest to the SD card holder.

I've desoldered the pins on the back of the shield, but I can't remove the IP Amp (IC3) yet. Any tips for how i should do this? I've tried using tweezers but still no luck. Here are some photos for help diagnosing any issues:

Removing a multi-pin chip intact is difficult without specialized tools. Usually I just cut the legs off and de-solder them one-by-one.

Looking at the chip datasheet the power and ground pins are in opposite corners. That means installing it in reverse will cause it to be powered up in reverse - most likely destroying the chip. So it is not likely to work if re-installed. You are better off with a new chip.

So I made a bit of a mistake and confused the IC3 component for the 12-bit DAC (IC2) when desoldering and clipping off the legs. I realized this and soldered the IC3 where it was supposed to be, so one problem was solved but another one was created. I can't find the 12-bit DAC when i search for it on the website to order a new one, is it possible that you have a link that I could use?

We don't stock these for individual sale. But both Mouser and DigiKey have them:

Can i plug a speaker or headphones into the port for the coding tests to check if the audio output is working, or do i need to install a speaker onto the wave shield?

You can plug a speaker or headphone into the jack on the shield.
