Review on 🔌 Waveshare ARPI600 IO Expansion Board with Arduino XBee Modules Support for Raspberry Pi Model A+/B+/2 B, Enhanced Interface for Easy Integration by Tim Thuss

I love the real time clock and A/D conversion, but it lacks a programmable chip that allows the Arduino to interact with the world and work with most shields. I bought a Dragino Yun shield to go with it and I can't figure out how to use the Raspberry Pi with it because there is no AVR chip to program with. There just isn't enough documentation or examples, and I highly recommend you avoid this product unless you consider yourself an Arduino and Raspberry Pi programming pro and can point the way for those of us who are less into it at the moment know about Although, I think one day I'll find out.
