Leveraging the innovative ultra-low-power oriented features, 3 Mbytes of embedded SRAM for STM32U5G9NJH6Q or 2.5 Mbytes for STM32U5A9NJH6Q, 4 Mbytes of embedded flash memory, and rich graphics features, the STM32U5x9J-DKx Discovery kits enable users to easily prototype applications with state-of-the-art energy efficiency, as well as provide stunning and optimized graphics rendering with the support of specific graphic features associated with each microcontroller.

The full range of hardware features available on the board helps users to enhance their application development by an evaluation of all the peripherals such as a 2.47‑inch RGB 480 × 480 pixels TFT round LCD module with MIPI DSI^® interface and capacitive touch panel, USB Type-C^® HS, Octo‑SPI flash memory device, Hexadeca‑SPI PSRAM memory device, eMMC flash memory device, Time-of-Flight and gesture detection sensor, temperature sensor, 20‑pin audio MEMS connector (for STM32U5G9J-DK1), and two 2.54 mm pitch double-row flexible expansion connectors for easy prototyping with daughterboards for specific applications (USART, LPUART, two SPIs, SAI, three I2C, SDMMC, ADCs, timers, and GPIOs).

The STM32U5x9J-DKx Discovery kits integrate an STLINK-V3E embedded in-circuit debugger and programmer for the STM32 microcontroller with a USB Virtual COM port bridge and comes with the STM32CubeU5 MCU Package, which provides an STM32 comprehensive software HAL library as well as various software examples.
