Overview

The STM32L4R9I-EVAL Evaluation board is designed as a complete demonstration and development platform for the STMicroelectronics Arm® Cortex®-M4 core-based STM32L4R9AI microcontroller, with 2 Mbyte of flash memory and 640 Kbytes of SRAM.

The full range of hardware features available on the board helps users to enhance their application development by an evaluation of all the peripherals (such as USB, USART, digital microphones, ADC and DAC, TFT LCD, MIPI DSI® display, LDR, SRAM, NOR flash memory device, Octo-SPI flash memory device, microSD™ card, sigma-delta modulators, CAN transceiver, EEPROM).

The daughterboard and extension connectors provide an easy way to connect a daughterboard or wrapping board for the user's specific application.

ST-LINK/V2-1 is integrated into the board, as the embedded in-circuit debugger and programmer for the STM32 MCU and USB Virtual COM port bridge.
