  • Serial Expansion HAT for Raspberry Pi, I2C Interface, 2-ch UART, 8 GPIOs

    There is only 1-ch UART port on the original Raspberry Pi, once it is used for terminal debugging, no more other serial device is allowed. What a poor situation. Now you have 2-ch extra UART, plus 8 programmable GPIOs, just bring this Serial Expansion HAT.


    • Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+
    • Onboard SC16IS752, expands 2-ch UART and 8 programmable GPIO through I2C, no extra pin required
    • It is stackable up to 16 this modules by setting the address jumper, that means up to 32-ch UART
    • Onboard multi LEDs for indicating the UART working status
    • Reserved I2C control pins, allows to work with other control boards
    • Comes with development resources and manual (examples in C and python)


    • Operating voltage: 3.3V
    • Expansion chip: SC16IS752
    • Control interface: I2C
    • Dimension: 65mm x 30mm
    • Mounting hole size: 3.0mm
