ماژول توسعه ورودی و خروجی 16 پین مدل MCP23017 با رابط I2C

The MCP23017 is capable of converting 16-bit parallel data to serial data of the IIC interface and converting each other. An internal integrated power-on reset (POR) circuit is reset to the device’s default state. Two independent programmable interrupt source outputs. The polarity toggle register configures the GPIO input polarity and can also be configured as an output. It can be set to use a pull-up resistor, and the IO configured as an input can use the interrupt function. The IO port has strong driving capability, and the current sinking and pulling current can reach 25mA.
