Create idea 16-ch IO Expansion Pin Module Board I2C Interface IIC Input Output MCP23017-E/SS for Computer Game Console

It is suitable for computer peripherals, game console control, smart home, sensor management, motor control, LED matrix drive and other fields, especially for embedded systems and multi-channel control projects. The module's default I2C address is configurable and compatible with standard 2.54mm pin headers (2x pin headers), which is convenient for plugging into breadboards or development boards, with easy connection and strong compatibility. The core uses MCP23017-E/SS, supports I²C communication protocol, has bidirectional 16-bit input and output control functions, and can greatly expand the number of IO ports of the main control chip (such as Ard-uino, Raspberry Pi, etc.). MCP23017 is a high-speed IIC interface. It supports IIC frequencies of 100KHz, 400KHz and 1.7MHz. The chip has 3 address pins and can set 8 different addresses. Therefore, 8 modules can be connected through two IIC buses to achieve up to 128 IO expansions.
