Description
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
- An older version using a CA3306 can be found as well: going around 10Msps, 6 bits. DIP based components.
- A possibly fast version of a 8 bit AD08200 ADC is available, going up to 12Msps.
- The latest 24Msps pHAT
