Quick2Wire I2C Port Expander Board Kit

The Quick2Wire® I2C Port Expander kit connects to our Raspberry Pi Interface board and gives you 16 additional GPIO pins which you can configure as inputs or outputs.

The Board and its components are supplied in kit form. You will also need an Interface board and a Raspberry PiTM computer with an SD card, power supply, keyboard, display and cables.

The board is supported by our Python library, and you’ll find easy-to-follow tutorials at

quick2wire.com

The board is based on the popular, powerful MCP23017 chip. It connects to the Interface board and other Quick2Wire boards via a 6-way ribbon cable (provided in the kit).
