The IO Pi Plus from AB Electronics is a digital I/O expansion board designed for the Raspberry Pi. It features 32 digital input/output channels, which are controlled via the I²C bus. The board uses two MCP23017 16-bit I/O expanders, allowing for easy expansion of the Raspberry Pi’s GPIO capabilities.
The board is stackable, meaning multiple boards can be added to a single Raspberry Pi, providing up to 128 I/O ports.
