STMicroelectronics STM32L4R9I-DISCO Discovery Kit
STMicroelectronics STM32L4R9I-DISCO Discovery Kit allows developers to explore the ultra-low-power oriented features, graphics performance (Chrom-ART Accelerator™), and DSI controller offered by the Arm® Cortex®-M4 core-based STM32L4R9AI Microcontroller. The STM32L4R9I-DISCO enables users to easily prototype applications with state-of-the-art energy efficiency, as well as offering stunning audio and graphics rendering, and direct support for an AMOLED DSI round LCD display. ST-LINK/V2-1 is integrated on the STM32L4R9I-DISCO as an embedded in-circuit debugger and programmer for the STM32 MCU.
The STM32L4R9I-DISCO offers everything required for users to quickly get started and easily develop applications. The full range of hardware features on the Discovery Kit includes USB OTG FS, microSD card, 8-bit camera interface, 16-Mbit PSRAM, Pmod and STMod+ connectors, IDD measurement, full-duplex I2S with an audio codec and stereo headset jack including an analog microphone, DFSDM with a pair of MEMS digital microphones on board, 512-Mbit Octo-SPI Flash memory device, I2C extension connector, and a 1.2" AMOLED display using a one data-lane DSI interface with a capacitive touch panel. The Arduino™ compatible connectors expand the functionality with a wide choice of specialized shields. The STM32L4R9I-DISCO Discovery Kit supports a wide range of Integrated Development Environments (IDEs) including IAR™, Keil® and GCC-based IDEs.
