Here is how it looks so far. This is the analog daughter that houses the Balanced input to Unbalanced + MUX. The last minute voltage dividers for implementing the loudness protection really makes the routing difficult.
This PCB just doesn't want to be made.
While the folks at OSH Park have been great helping me, I have lost 4-5 weeks just waiting for packages that never show up. UPS innovation, USPS, Canada Custom, Canada Post all have their fingers in the pie. Not sure if/when this will be fixed as this is the 3rd shipment in a row that hasn't show up or extremely late.
Here is the Canada Post tracking. Kind of braindead as I don't have the tracking# until after receiving it. It is as useful as an alarm clock that you have to wake up to check.
These days you have to have some level of ESP to order stuff well ahead of time to work with long lead time. I got some TI NE5532, some HC4052 MUX and some buttons for this project. I now have the parts for the daughter card.
I ordered some STM32F030 over the weekend. I have already used 8 of them out of 20! At $0.44 a piece, they are around the jelly bean logic chips prices so I have been using them for the last half dozen projects here.
