I bought this bad boy. Seems cool. Thought maybe I could brute force my way into AM radio land with it.

Also a good project for fpga. Microcontrollers are going to be too slow.

A noticeable problem is the missing of the pinout

AD:DA pinout

This appears to be the same product and I can at least confirm that this pinout does work for the DA side of things.

I wrote a quick test program to service it with a ramp function with an arduino. Good idea to sanity check before diving into the deeper waters of fpga.
