Module: A high speed ADC for the RaspberryPi

The board in red:


What is it supposed to do?

I've always needed a small upgrade to the existing raspberry ADC extensions, would love something in the 20-Msps range. Let's see if one can do it! Never tried smd, and thinking of using both smd and dip.. interesting learning curve ahead.

I've tried 3 different versions, increasing in complexity

The echOmods project and its prototypes (so Bomanz) are open hardware, and working with open-hardware components.
