Introduction

The STM32H7B3I-DK Discovery kit is a complete demonstration and development platform for STMicroelectronics Arm®

Cortex®-M7 core-based STM32H7B3LIH6QU microcontroller. This microcontroller features four I2C interfaces, six SPIs with four

multiplexed full-duplex I2S interfaces, two SDMMC controllers, five USARTs, five UARTs, one ULPUART, one TTFD-CAN, one

FD-CAN, two 16-bit ADCs, two 12-bit DACs, two SAIs, two Octo-SPI interfaces, two analog comparators, one SPDIF-RX,

DFSDM (8 channels / 8 filters), one USB HS OTG and one USB FS OTG, DCMI interface, FMC interface, TFT LCD controller

interface, JTAG, and SWD debugging support.

This STM32H7B3I-DK Discovery kit offers everything required for users to get started quickly and develop applications easily.

The hardware features on the board help to evaluate the following peripherals: USB HS OTG, microSD™ card, 8-bit camera

interface, audio DAC stereo with audio jack input and output, 128-Mbit SDRAM memory, 512-Mbit Octo-SPI Flash memory,

Wi‑Fi® module (802.11 b/g/n compliant), I2C extension connector, FD-CAN, 20-pin microphone MEMS connector with DFSDM

interface, 4.3-inch TFT-LCD (480*272) using an RGB interface with a capacitive touch panel. The ARDUINO® Uno V3

compatible connectors and STMod+ connector allow easy connection of extension shields or daughterboards for specific

applications.

The integrated STLINK-V3E provides an embedded in-circuit debugger and programmer for the STM32 MCU.

2.1 Product marking

Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference

design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will

be liable for any customer usage of these engineering sample tools as reference designs or in production.

“E” or “ES” marking examples of location:

• On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the

STM32 datasheet “Package information” paragraph at the www.st.com website).

• Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.

This board features a specific STM32 device version, which allows the operation of any bundled commercial

stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number

and is not available for sales.

In order to use the same commercial stack in his application, a developer may need to purchase a part number

specific to this stack/library. The price of those part numbers includes the stack/library royalties.

2.2 Codification

The meaning of the codification is explained in Table 2. The order code is mentioned on a sticker placed on the

top side of the board.

6Getting started

1. Ensure that the JP1 jumper is set to STLK.

2. Connect a Type-A to Micro-B USB cable from the STM32H7B3I-DK board (Connect USB STLINK CN14) to

a PC to power the board. Then LD5 (+5V) and LD4 (STLINK COM) light up.

3. Take advantage of three graphical stacks running on the same board with many featured applications for

each selected Sub-Demo:

– Menu launcher

– Audio player TGFX application (MP3 support)

– Clock and Weather with Alarm feature

– Video player TGFX application (enabled)

– TGFX Graphic demonstration

– STemWin Graphic demonstration

– EWZ Graphic demonstration

4. The demonstration application software as well as other software examples and applications for exploring

STM32H7 features are available from STM32H7B3I-DK.

Note: The audio and video player applications play audio and video files from the microSD™ card.
