GERUI 5pcs MCP23017 Serial Interface I2C Bidirectional 16 Bit I/O Expander Pins 10MHz Module

Three hardware address pins allow up to eight devices on the bus mcp23017 serial interface module IIC I2 C SPI mcp23s17 bidirectional 16-bit I/O expander pins 10MHz serial interface module High-speed I2 C interface (mcp23017): - 100 kHz - 400 kHz - 1.7 MHz Compact design: an internal integrated power on reset circuit (POR) is reset to the standard state of the device. The two opposites become the exit of the interrupt source. The polarity switching register configures GPIO input polarity. Interfaces: 16-bit remote bi-directional I/O port; high-speed I2C interface (MCP23017); configurable interrupt output pins.
