STM32L4R9I-EVAL - development kit with STM32L4R9AI microcontroller

Description

The STM32L4R9I-EVAL Evaluation Kit was designed to demonstrate the capabilities of the STM32L4R9AI microcontroller based on the ARM ^® Cortex ^® -M4 core. The microcontroller is equipped with 4 I ² C ports, three SPI and six USART, CAN port, two SAI ports, 12-bit ADC converter, 12-bit DAC converter, built-in 640 KB SRAM memory, FLASH memory with 2 MB capacity, two Octo-SPI interfaces, USB OTG FS port, LCD-TFT controller, MIPI DSI host, FMC controller, 8 ... 14-bit camera interface and support for debugging with JTAG.

The board offers the possibility of testing and development of applications using a large number of peripherals (USB, USART, digital microphones, ADC and DAC converters, TFT LCD, MIPI DSI LCD, LDR, SRAM, NOR Flash memory, Octo-SPI Flash memory, microSD card, modulators sigma-delta, CAN transceiver, EEPROM). Mounted connectors allow easy attachment of extensions.

The board also has a built-in debugger / ST-LINK / V2-1 programmer, which can also be used as a virtual COM port.
