Waveshare AD/DA Expansion Sheild Board for Raspberry Pi
This board worked well for me once I got some info from the waveshare website and GitHub. It connects directly to the Raspberry Pi. It is better featured than other ads1256 boards, and ethink had the best price. I want to thank ethink for the help with the order, it got stuck at SFO. My customer representative was first class.

Works perfect as expected!
Very easy to use. Works with the python3 library in raspberry pi 4B

Very noisy
The WiFi of a Raspberry Pi puts ~ 10 millivolts of noise into both the ADC and the DAC -- these 16-bit components should have noise levels below 100 microvolts. That makes it useless for my application. If you don't use WiFi, you might be able to get it to work. It does work well with a Teensy 4.0 (an Arduino on steroids), which has no WiFi but does have a high-speed USB serial interface.
