Introduction

The STM32H7S78-DK Discovery kit is a complete demonstration and development platform for the Arm

Cortex

‑M7

core‑based STM32H7S7L8H6H microcontroller.

The STM32H7S78-DK Discovery kit includes a full range of hardware features that helps the user to evaluate many peripherals,

such as USB Type-C

, Octo‑SPI flash memory and Hexadeca‑SPI PSRAM devices, audio codec, digital microphones, ADC,

flexible extension connectors, and user button. The four flexible extension connectors allow easy and unlimited expansion

capabilities for specific applications such as wireless connectivity, analog applications, and sensors.

The STM32H7S7L8H6H microcontroller features three I

C buses, six SPI ports, three USART ports, two SDMMC ports, two

CAN ports, an Ethernet port, two SAI ports, two 12‑bit ADCs, an embedded step-down converter, two Octo‑SPI memory

interfaces, one Hexadeca‑SPI interface, USB OTG HS port with power delivery, LCD‑TFT controller, flexible memory controller

(FMC), 8‑ to 14‑bit DCMI interface, JTAG, and SWD debugging support.

The STM32H7S78-DK Discovery kit integrates an STLINK-V3EC embedded in-circuit debugger and programmer for the STM32

MCU, with a USB Virtual COM port bridge and the comprehensive MCU Package.
