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 I
2
C interfaces, six SPIs with four
multiplexed full-duplex I
2
S 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), I
2
C 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.
