STM32L4R9I-DISCO

STM32L4R9I-DISCO is a discovery kit with STM32L4R9AI MCU. The 32L4R9IDISCOVERY kit is a complete demonstration and development platform for the Arm® Cortex®-M4 core-based STM32L4R9AI MCU. Leveraging the innovative ultra-low-power oriented features, 640Kbytes of embedded RAM, graphics performance (Chrom-ART Accelerator™) and DSISM controller offered by the STM32L4R9AI, the 32L4R9IDISCOVERY kit enables users to easily prototype applications with state-of-the-art energy efficiency, as well as providing stunning audio and graphics rendering with direct support for an AMOLED DSI round display. For even more userfriendliness, on-board ST-LINK/V2-1 debugger provides out-of-the-box programming and debugging capabilities. The STM32L4R9AI MCU features 4 I2Cs, 5 USARTs, ULP UART, 3 SPIs, 2 SAIs, SDIO, USB 2.0 full-speed OTG, 2 CANs, FMC parallel synchronous interface, 12bit ADC, 12bit DAC, 2 ULP analogue comparators, 2 op-amps, 2 data-lane DSI display, digital filter for sigma-delta modulation.
