Eight Serial Ports 2-Layer Stackable HAT for Raspberry Pi _RPI_HAT_RTC At the heart of theThe latest versions of the Raspberry Pi have up to four UART ports on the GPIO connector, but you cannot use them without a physical layer transceiver. The Eight Serial Ports HAT uses all four ports of the Raspberry Pi, plus eight additional ports from two 32 bit ARM Cortex processors, to implement all the common serial ports in use today. The processors talk to the Raspberry Pi using only the I2C port, with the hardware address selectable from a DIP
