IIC Input Output Expansion Board MCP23017 I2C Interface 16Bit 16-Channel I/O Expansion Module Pin Board Converter

Description:
This module is the 16 way IO extension module of the 12C interface, and built in the MCP23017 chip of MicroChip. 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, 400KHz and 1.7MHz. The chip has 3 address pins, which can be set up for 8 different addresses. So 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions.
This module is flexible in configuration and strong in driving ability. There are many parallel connections.
