I2C 16 Input -Output Port Expander MCP23017

 

I2C 16 Input -Output Port Expander MCP23017

The IO Expander Board is based on the Microchip MCP23017 Expander Chip. This high-performance IC, allows connection to a range of High-Speed I²C buses, including the standard 100kHz bus, as well as the newer 400kHz and 1.7MHz bus standards. 

ORDER CODE: RDL637

Features:

• Includes Microchip MCP23017 16-Bit I/O Expander Chip

• Board can be controlled with High-Speed I²C Connection.

• Standard Male Headers for Board Interfacing.

• Suitable for 5V Systems.

• Three hardware address pins to allow up to eight devices on the bus

MCP23017 Features:

• 16-bit remote bidirectional I/O port - I/O pins default to input
