32 Channel Digital Expansion HAT for Raspberry Pi

Description 32 Digital Inputs/Outputs Control via the Raspberry Pi I2C port Stack up to 4 IO Pi boards on a single Raspberry Pi Solder jumper selectable I2C addresses External 5V Input with isolation solder jumper Based on the MCP23017 from Microchip Technologies Inc  The 32 Channel Digital Expansion HAT for Raspberry Pi is a 32-channel digital expansion board designed for use on the Raspberry Pi. The board is based around the MCP23017 16-bit I/O expander from Microchip Technology Inc. A pair of MCP23017 expanders are included on the board allowing to connect up to 32 digital inputs or outputs to the Raspberry Pi.  The IO Pi Plus Expander is powered through the host Raspberry Pi using the GPIO port and extended pins on the GPIO connector allow to stwack the IO Pi Plus along with other expansion boards.
