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

Serial Expansion HAT for Raspberry Pi, I2C Interface, Provides 2-ch UART and 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.

Features

• 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)

Specifications

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