ST STM32L4P5G-DK Bedienungsanleitung

Introduction

The STM32L4P5G-DK Discovery kit is a complete demonstration and development platform for the STMicroelectronics Arm®

Cortex®-M4 core-based STM32L4P5AGI6P microcontroller with four I2C buses, three SPI and six USART ports, CAN port, two

SAI ports, 12-bit ADC, 12-bit DAC, internal 320-Kbyte SRAM and 1-Mbyte flash memory, two Octo‑SPI memory interfaces,

touch-sensing capability, USB OTG FS port, TFT LCD controller, flexible memory controller (FMC), 8- to 14-bit DCMI interface,

and JTAG debugging support.

The STM32L4P5G-DK Discovery kit is used as a reference design for user application development before porting to the final

product.

The full range of hardware features on the board helps the user evaluate all the peripherals (USB OTG FS, Octo‑SPI flash

memory and PSRAM memory device, eMMC, and others) and develop applications. The ARDUINO® Uno V3 and STMod+

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.
