The MCP23017, a 16-bit I2C GPIO expander, has always been a tasty chip. With 16 GPIOs addressable over I2C, proper push/pull outputs, software-enabled pull-ups, eight addresses, maskable interrupts ...

Promising to be a cost-effective solution for adding functions while reducing power, the CAT9534 eight-bit GPIO expander targets I2C and SMBus-based systems. The device is pin-for-pin and functionally ...
I always like projects that bring the Raspberry Pi and Arduino together, however gently. It's what the world needs, a bit more harmony. Check out this little one on GPIO programming on a Raspberry Pi ...
