| ST STM32H7B3I Discovery Kit |
| ########################### |
| |
| Overview |
| ******** |
| |
| The STM32H7B3I-DK Discovery kit is a complete demonstration and development |
| platform for STMicroelectronics Arm® Cortex®-M7 core-based STM32H7B3LIH6QU |
| microcontroller. |
| |
| The STM32H7B3I-DK Discovery kit is used as a reference design for user |
| application development before porting to the final product, thus simplifying |
| the application development. |
| |
| The full range of hardware features available on the board helps users enhance |
| their application development by an evaluation of almost all peripherals (such as |
| USB OTG_HS, microSD, USART, FDCAN, audio DAC stereo with audio jack input and output, |
| camera, SDRAM, Octo-SPI Flash memory and RGB interface LCD with capacitive touch |
| panel). ARDUINO® Uno V3 connectors provide easy connection to extension shields or |
| daughterboards for specific applications. |
| |
| STLINK-V3E is integrated into the board, as an embedded in-circuit debugger and |
| programmer for the STM32 MCU and the USB Virtual COM port bridge. The STM32H7B3I-DK |
| board comes with the STM32CubeH7 MCU Package, which provides an STM32 comprehensive |
| software HAL library as well as various software examples. |

| System Clock |
| ============ |
| |
| The STM32H7B3I System Clock can be driven by an internal or external oscillator, |
| as well as by the main PLL clock. By default, the System clock is driven |
| by the PLL clock at 280MHz. PLL clock is fed by a 24MHz high speed external clock. |
| |
| Serial Port |
| =========== |
| |
| The STM32H7B3I Discovery kit has up to 8 UARTs. |
| The Zephyr console output is assigned to UART1 which connected to the onboard |
| ST-LINK/V3.0. Virtual COM port interface. Default communication settings are |
| 115200 8N1. |

| Programming and Debugging |
| ************************* |
| |
| See :ref:`build_an_application` for more information about application builds. |
| |
| |
| Flashing |
| ======== |
| |
| Flashing operation will depend on the target to be flashed and the SoC |
| option bytes configuration. |
| It is advised to use `STM32CubeProgrammer`_ to check and update option bytes |
| configuration and flash the ``stm32h7b3i_dk`` target. |
| |
| |
| Debugging |
| ========= |
| |
| You can debug an application in the usual way. Here is an example for the |
| :ref:`hello_world` application. |

| Take note that CANFD pins are shared with STMOD+ connector (P1), so please check |
| `STM32H7B3I_DK board schematics`_ for possible collisions if using that connector. |
