Waveshare Serial Expansion Board, Compatible with Raspberry Pi, with I2C Interface 2-CH UART and 8 GPIOs

• Onboard SC16IS752, this module is for Raspberry Pi series boards to have 2-ch extra UART and 8 programmable GPIOs
• 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
• Operating voltage: 3.3V, Control interface: I2C, Dimension: 65mm x 30mm, Mounting hole size: 3.0mm
• Provide online development resources and manual (examples in C and python)

Overview 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. Features Standard Pi 40PIN GPIO extension header, supports Raspberry Pi series boards 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 with development resources and manual (examples in C and python) Specifications Operating voltage: 3.3V Expansion chip: SC16IS752 Control interface: I2C Dimension: 65mm x 30mm Mounting hole size: 3.0mm User Manual waveshare.com/wiki/Serial_Expansion_HAT?amazon PACKAGE CONTENT Note: Raspberry Pi in the photos is NOT included. 1.
