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:
