The UART available on the RSP 40-pin header enables direct serial communication and provides a reliable debug interface if other communication interfaces fail.

This HAT provides a galvanically isolated FTDI-based UART-to-USB interface for robust communication and protection against ground potential differences and noise coupling. As part of the BE-IIS HAT++ ecosystem, it is stackable with other HATs from the portfolio for seamless system expansion and simplified system integration.

The open-source BE-IIS Installer configures this HAT—and all other HATs in the BE-IIS portfolio—in minutes, without requiring in-depth Linux knowledge.
