I have AWDSP boards available with ADA DSP and Microcontroller already soldered, which is bit too much for a novice anyway.

Yes I can. I have a reflow oven and SMD rework station. Have done a lot of smaller no-lead chips and looking for something more challenging

I need a good ADC for measurements, I was looking into the SDR-widget. I was thinking maybe I could connect the I2S bus to a USB board like the Amanero. What do you suggest?

??? The Audio Widget is a USB interface ??? Maybe I don't quite understand what you are asking for? How good an ADC are you after? Build or buy? Big project or just need to get to work measuring?

The SDR widget is a USB Audio Class 2 interface for an AK5394A. You could build it. I think you need to make boards and flash the USB chip to get it going. The original supply are long gone. There are few comparable alternatives.
