Isolated USB to Dual UART Industrial HAT++ for Raspberry Pi
In Production
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.

Product Description
The UART Industrial HAT is a Raspberry Pi HAT+ compliant board providing reliable UART access for debugging, service, or additional USB-to-UART interfaces.
It integrates an SC16IS752 dual UART controller and an isolated UART interface with galvanic isolation between the host system and the external interface. In fallback scenarios, the native Raspberry Pi UART can also be used.
Applications
- UART debugging and service interfaces
- Sevelopment and prototyping
- Education and training environments
- Protocol gateway and converter design
- Industrial communication evaluation and testing
