There's also this: https://store.digilentinc.com/dmm-shield-7-function-digital-... from Digilent. Haven't tried it, but it looks interesting.

That is pretty cool, it uses the HY3131 chip (http://www.hycontek.com/wp-content/uploads/DS-HY3131_EN.pdf) and is another example of an entity that has the resources to design a robust analog front end just using one in a chip.
FWIW I ordered one to see if I can get it working on one of my many ST Micro Nucleo boards.
