Centipede Shield V2
The Centipede Shield is SO EASY to use! I have two of them connected to an Arduino Mega and can address 128 ports as any combination of input or output, to turn on LEDs or relays, or to read the status of a switch or relay, for example. They are beautifully engineered, ridiculously inexpensive, the tech support is outstanding, and the assembly is trivial. In fact, you don't even need to install the headers if you don't need to use it as a shield. In my case, I'm using it with a Mega, so I just soldered pins for SDA, SLC, power, and ground - that's all you need! The board can be powered by your Arduino or a separate power supply -- just be sure you connect all grounds together. A fantastic product!
