1-10pcs MCP23017 16Bit I/O Expansion Board Module Pin PCB IIC I2C Interface To Gipo Converter 25mA1 For Arduino
1. Description:This module is the 16 way IO extension module of the 12C interface, and built in the MCP23017 chip. The function of the chip is complete. Each IO can be arbitrarily configured as input or output, and a pull up resistor can be set, and the interrupt function can be enabled for the IO configured as input. The IO interface has a strong driving capacity, and the current and current can reach 25mA. MCP23017 is a high-speed IIC interface. It supports the IIC frequency of 100KHz, 40
