Discovery kit with STM32F730I8 MCU
Introduction
The STM32F7308-DK Discovery kit is a complete demonstration and development platform
for the STMicroelectronics Arm
®
Cortex
®
-M7 core-based STM32F730I8K6 microcontroller. It
features the following interfaces: three I
2
Cs, five SPIs with three multiplexed simplex I
2
S,
2xSDMMC, FMC, Quad-SPI. It also features four USART and four UART peripherals, one
CAN bus, three 12-bit ADCs, two 12-bit DACs, two SAIs, internal 256
Kbytes of SRAM,
64
bytes of Flash memory, one USB OTG HS internal PHY, USB OTG FS and SWD
debugging support. This STM32F7308-DK Discovery kit offers everything required for users
to get started quickly and develop applications easily.
The full range of hardware features on the board helps users to evaluate almost all
peripherals (USB OTG HS and FS, USART, SAI Audio DAC stereo with audio jack input and
output, ST-MEMS digital microphones, external PSRAM, Quad-SPI Flash memory, LCD with
capacitive multi-touch panel, and others) and develop applications. Arduino
™
Uno V3,
Pmod™ and STMod+ connectors allow easy connection of extension shields or
daughterboards for specific applications.
The integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and programmer for
the
STM32 microcontroller.
The STM32F7308-DK Discovery kit comes with comprehensive free software libraries and
examples available with the STM32Cube™ MCU Package.
