STM32H743 CAN + USB-HS Dev Board

An STM32H743 development board with on-board USB-HS and CAN-FD (up to 8Mbit/s)

This design is still a work in progress, functionality has not been tested.

Features

STM32H743 microcontroller with 116 I/O pins exposed
CAN-FD using DE-9 connector using industrial standard pinout
High Speed USB 2.0 using USB3300 ULPI PHY
128Mbit QuadSPI NOR flash
SWD debug using MIPI-10 Cortex Debug connector
USB-C ports for DFU and HS
Power path switching from HS and DFU port and backfeed prevention
RGB LED
Boot/Reset buttons

Programming

The board can be programmed via the DFU port using the DFU bootloader by pressing BOOT and RESET to put the board into DFU mode.

The board may also be programmed/debugged using the MIPI-10 Cortex Debug connector.

Development

The board supports any toolchain that supports the STM32H743 microcontroller, including the STM32CubeIDE and Zephyr. Zephyr device trees and board configurations will be available in the future.
