DEVMO MCP23017 I2C Interface 16bit I/O Extension Module Pin Board IIC to GIPO Convert Compatible with Ar-duino IIC Input and Output Expansion Board
- This module is flexible in configuration and strong in driving ability. There are many parallel connections.
- 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.
