XICOOLEE Serial Expansion Module I2C Interface for Raspberry Pi, Adopts SC16IS752 Chip 8-bit I/O Expander 2-Channel UART 8 GPIOs Expansion, Slide Switch

• The settings of I2C address and the selection of interrupt pins are designed with slide switch, convenient for users to set
• This serial IO expander is onboard SC16IS752, can expand 2 serial ports and 8 programmable IO through I2C, does not occupy extra pins
• By changing the address jumper, up to 16 modules can be connected at the same time, that is, 32 serial ports can be expanded
• Multiple onboard indicators, easy to check the working status of the extended serial port
• Serial Expansion Module not only is suitable for Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+/4B,but also is reserved I2C control interface for easy access to other main control boards
