The STM32L4R9I-EVAL evaluation board is designed as a complete demonstration and development platform for STMicroelectronics’ Arm® Cortex®-M4 core-based STM32L4R9AI microcontroller with: four I²C buses, three SPI and six USART ports, CAN port, two SAI ports, 12-bit ADC, 12-bit DAC, internal 640-Kbyte SRAM and 2-Mbyte Flash memory, two Octo-SPI memory interfaces, touch-sensing capability, USB OTG FS port,LCD-TFT controller, MIPI DSI host controller, flexible memory controller (FMC), 8- to 14-bit camera interface, and JTAG debugging support.
The full range of on-board hardware features helps the user to evaluate all the peripherals (USB, USART, digital microphones, ADC and DAC, TFT LCD, MIPI DSI LCD, LDR, SRAM, NOR Flash memory device, Octo-SPI Flash memory device, microSD card, sigma-delta modulators, CAN transceiver, EEPROM) and to develop applications. Extension headers allow easy connection of a daughterboard or wrapping board for a specific application.
An ST-LINK/V2-1 is integrated on the board, as an embedded in-circuit debugger and programmer for the STM32 MCU and the USB virtual COM port bridge.Key Features
