Never run out of I/O on your Arduino again with this new shield

A new Kickstarter campaign has caught my eye after running out of I/O ports on my Arduino during a recent project. The 64 I/O Arduino Shield is designed to fit a standard Arduino Uno and will expand its I/O from the standard 20 pins to 64 pins thanks to the use of the Arduinos I2C bus.

The shield appears to use the MCP2301, a 16-Bit I2C I/O expander, and the Kickstarter documentation says that thanks to an address changer, two shields can be used in conjunction to form 128 GPIO pins. The 64 I/O Arduino Shield can be purchased for about $28 US with shipping included.

As someone who uses Arduinos for most of his projects, I will be picking up a few of these to keep in the workbench for future projects. Head over to the source link to back the project for yourself, and let us know if you make any cool projects with it!
