Serial Expansion HAT for Raspberry Pi, I2C Interface, 2-ch UART, 8 GPIOs (WS-15667)
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.
