16-Ch IO Expansion Pin Module Board Interface IIC Input Output MCP23017-E/ for Computer Game Console Designed for versatility, this IO expansion module is ideal for computer peripherals, game console controls, smart home systems, sensor management, motor control, and LED matrix driving. It's particularly useful in embedded systems and projects requiring multiple channel controls. Featuring a user-configurable address, this module integrates seamlessly with standard 2.54mm pin headers. Its compatibility with breadboards and development boards ensures easy connections and enhances its adaptability across various platforms. At the heart of this module is the MCP23017-E/ chip, which supports the I²C communication protocol. It offers bidirectional 16-bit input and output control capabilities, significantly increasing the number of IO ports on main control chips like for and for . The MCP23017 chip operates over high-speed IIC interfaces, supporting frequencies of 100KHz, 400KHz, and 1.7MHz. This feature ensures rapid data transmission and efficient performance in complex control systems. Equipped with 3 address pins, the chip can be set to 8 different addresses, allowing up to 8 modules to be connected via two IIC buses. This setup enables a substantial expansion, supporting up to 128 IO ports for extensive project scalability.
