STMicroelectronics STM32L4R9I-EVAL Evaluation Board
STMicroelectronics STM32L4R9I-EVAL Evaluation Board offers a complete demonstration and development platform for the STMicroelectronics Arm® Cortex®-M4 core-based STM32L4R9AI microcontroller. The full range of hardware features on the STM32L4R9I-EVAL Evaluation Board allows developers to access and evaluate the STM32L4R9AI peripherals, including USB, UART, 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, and EEPROM.
ST-LINK/V2-1 is integrated on the STM32L4R9I-EVAL, as an embedded in-circuit debugger and programmer for the STM32 MCU and the USB virtual COM port bridge. The JTAG/SWD connector and ETM Trace Debug Connectors allow external debugging.
The STM32L4R9I-EVAL includes two LCD display daughterboards, one with a 1.2" MIPI® DSI round LCD display, and one with a 4.3" TFT LCD RGB display.
The STM32L4R9I-EVAL Evaluation Board supports a wide range of Integrated Development Environments (IDEs) including IAR™, Keil® and GCC-based IDEs.
