High-Precision AD/DA Expansion Board for Raspberry Pi 4B/3B+/3B/2B/Zero/W/Zero WH and Jetson Nano,Add High-Precision AD/DA Functions to Pi. Onboard ADS1256 8-CH 24bit ADC and DAC8532 2-CH 16bit DAC

Great product! The ADS1256 on this board has been incredibly useful in my development with various microcontrollers.

I’m using it with the Raspberries pi3, Once you figure out and locate the software for it it works fine. The build quality is very good. The fact that they have test jumpers that let you measure and onboard photo meter and potentiometer makes it easy to check out your software before you add an external sensor. I would buy more products from this manufacture given the quality.

This is a great little board with lots of different configuration options. It's great that it can do both differential and single ended measurements.

This is a great little board that I’m currently using to measure the voltage of my solar battery. Reliable so far!

The documentation they have posted on their website is only tested "for the Pi 3b" so it won't work on the Pi 4 despite what they are claiming. The product comes with no documentation itself, only a box with the hat and some screws.

The documentation is good. Just open box and run.

A little complex to figure out how to use but then again I'm just a newbie. One day I'll get around to it

Please consider making it cascade multiple boards.
