Mouser mostly with just a few exceptions at Farnell (parts I could not find at Mouser).
I will publish the BOMs sometimes this week hopefully. 😉
BOM release is delayed to the end of next week - I still need do a final reading and a bit of cleanup before let it go.
Hi,
While waiting for the PCBs to show, you may find the BOM for the MCU control card here 😉
Remark:
the components necessary for an UGS are listed in the yellow column - you need to ignore others.
Also the Mouser basket need to be complemented with some parts in the connector section and display option according to your own preference (mine are listed in the first Mouser column and I use the newheaven VFD from my old UGS AI)
I will publish next the BOM for the others cards (no rush yet since the PCBs have not yet arrived)

Adding supplies 😉
Link to the BOMs:
- carte MCU / MCU board
- carte preamp / preamp board - besoin de 2 / need 2
- carte alim logique / logic supply board
- carte alim primaire / primary supply board

Hi SB, good catch.
The schematics of the left and right preamp v1.2 has not been uploaded by Alex yet.
I already sent an email - hopefully he will find some bandwith to do the upload soon. Wait&See.
News from the french forum : PCB are on their way to Alex's.
Eric will make the dispatching on early 2016 (vacations in between).
Best seasons greetings

Hi Eric & Maousse. I'm working through the BOM and I have a few questions for the Processor board. According to the BOM there are 4 options. They are USB, Wifi, Audio Ext & Misc
Can you describe in more details what are each option for?
Also on the BOM there is a very expensive optical encoder at 43$. The previous UGS All-Inclusive used a much cheaper Bourns encoder at 5.87$ (Mouser Part No. ECW1J-B24-AC0024L ). Is the cheaper model still compatible with the new controller?
Thanks
SB

Hi SB,
The processor board has been designed as a general purpose version that extends much beyond what is required to build an UGS preamp.
Alex added these options for debug and trial purpose only (they may or may not used in the future - ex for a DAC).
To make it short, DO NOT POPULATE the parts listed in the WIFI, USB2 and AUDIO columns.
It will be always time to add parts later on such as WIFI if Alex comes with a supported firmware for it which is presently not the case.
The bourns encoder you refer to is a mechanical version, so yes it can be used as well providing you configure the board properly (refer to the BOM notes and schematics).
Just a remark about it - you need to add an extra switch if you use this mechanical encoder (for on/off purpose).

Here my own complete preamp Parts List using Eric separate and some how complex lists. It has more details for each part, shows the different options, and includes Eric comments. We can use it to calculate the complete project and I find it easier to use than the pdf lists.
Comments are welcome.
