I did some work the last couple of days, finding the IC's at Mouser.

Here are the links that I think are right. I found a 157, but it seemed like it was going to be a tight fit in the footprint, so I am not including it yet.

74HCU04

PCM2707

SRC4192

WM8741

HC1G08

HC1G14

TPS3809

3.3 Volt Reg

5Volt Reg

Ferrite

I think the apple remote was just part of the wiring diagram, looks like the diagram was written for a different project.

Looking at the web page for the code, it said a Sony TV remote, so I agree.

To access the shared mouser bom listings... go to ;

Mouser Electronics - Electronic Component Distributor. Under Project and cart sharing...

Enter '6586cd42e9' for wm8741 digital receiver 1 -- missing pin headers - not sure of size

Enter '40fde56eec' for wm8741 digital receiver 2 -- missing pin headers - not sure of size & crystal

Enter 'e31d00d376 ' for i2c level shifter -- missing pin headers

Enter '27ccd0aaa1' for super mini dac v2.0 -- just started this one


If you get any further than I have please share your results.

If you find any errors, please keep me posted.

Thanks.

Hi Merlin,

Thanks for sharing. I would just make sure to only get thin film or metal film resistors. Thick film are not ideal for this application.

That's great, can you export your BOM into a spreadsheet or share it?

Here it is!

If you make changes, please share with us

Please rename the extension to .xls since it is an Exel file

Thanks

I have not received my board yet so the Digikey list is just preliminary.

Priyesh, could you please let us know the package type for each chip? Just to make sure we're on the right track.

Thanks

Glad to see that you are planning to the hifiduino code.

There are two blogs: hifiduino.blogspot.com describe mostly the code for WM8741; hifiduino.wordpress.com describes the code for ES9018

The code for WM8741 uses a serial LCD and a Sony Remote
The code for ES9018 uses a parallel LCD and an Apple Remote

The code for the ES9018 is "nicer" (since i got more experience). So for example you can take the code for the parallel LCD here and use it in the code for the WM8741.

Make sure you use the 5v to 3.3v level converter. The Wolfson parts are NOT 5V tolerant.

I ordered a duino uno + LCD for my Dual Mono BII so I have to do the same for the Wolfson or it will get jealous!
