The STM32U585 on board the Arduino Uno Q (release date 2025-10-25).

Preliminary port based on:

Draft until verification on actual hardware. VID and PID are not yet known / documented.

Thanks for the initial PR!

Don't include every MCU pin in board. They are automatically available in microcontroller.pin. board should only reflect board-specific names (aka silkscreen) or uses (connected to other things on the board.)

thanks for the feedback. I'll remove those and add board related signals as well.

I wonder what is available on multiple headers on the bottom, or are those only the Broadcom chip signals?

The bottom JMEDIA 60-pin header has 1.8V signals for the Dragonwing MIPI camera and display support. The JMISC 60-pin header has line/headset audio plus a mix of 3.3V GPIO from the STM32 and 1.8V GPIO from the Dragonwing.

Does assigning a VID and PID make sense here? By my reading of the UNO Q datasheet (see page 13: 4.2 Block Diagram), it doesn't look like the STM32U585 has access to the USB-C port. It seems the board is set up for Debian running on the Dragonwing MPU to program the STM32 over SWD and do RPC bridge stuff over UART and SPI channels.
