I needed a whole lot of IO ports for my Raspberry. I bought a total of seven of these. This board was super easy to use both for configuring input/output ports. Interrupts are a nice feature, as well as the ability to programmatically pull input port high.Accessible on port x20 - x27 (default), so you can run 8 of these for a total of 64 IO ports.I was able to convert the C examples to Ruby without any fuss.Pro:* Easy to use for IO expansion.* Nice features (IO configuration, pull ups, interrupts)* Great example code (C and Python).Cons:* Hard to mount as there is only a single set of holes in the board (ideally there would have been a hole on each corner).* Soldering the address jumpers (A0/1/2) too a little work

The libaray is addressed to 0x20 but I found it works at 0x27 right out of the box, so you'll have to adjust for that to avoid my initial annoyance.

I needed a MCP23017 in a hurry and Amazon got this to me in two days. The board comes with connector wires allowing me to quickly connect it to my TI EK-TM4C1294XL eval board for testing. The I2C interface already comes with 10K pull ups so no external wiring was needed. I was able to read GPIO inputs, control outputs and setup interrupts on input state changes. Everything worked as expected. The only issue (I knew this when I bought it) is another MCP23017 cannot be daisy chained on the I2C bus without soldering on the expansion header. Additional work is needed to change the I2C address as it is hard wired to 0x27 out of the box. Other than that, I'm very happy with my purchase.
