BE-IIS documentation explains how the hardware fits into a Raspberry Pi based system and how the Linux integration is structured.

Every HAT++ product uses a defined hardware configuration. The installer builds and installs the required Device Tree overlays, modules and persistent device names. The result is a predictable interface instead of a one-off manual configuration.

Documentation scope

This first edition focuses on the current hardware portfolio:

• The HAT++ system and instance modes
• Single Pair Ethernet, CAN-FD, RS-485, UART and LAN products
• GMSL2 camera hardware and the camera software flow

Detailed resource links, downloads and external references will be added separately.
