New Riverdi STM32 Embedded Display 5"

Riverdi offers a new 5-inch display module based on new STM32U5 in its top-tier STM32 Embedded Displays series, with capability to use pre-installed presets in TouchGFX tool for free.


The STM32U5A9J-DK Discovery kit is a complete demonstration and development platform for the STM32U5A9NJH6Q microcontroller, featuring an Arm® Cortex®‑M33 core with Arm® TrustZone®.

Leveraging the innovative ultra-low‑power oriented features, 2.5 Mbytes of embedded SRAM, 4 Mbytes of embedded flash memory, and rich graphics features, the STM32U5A9J-DK Discovery kit enables users to easily prototype applications with state-of-the-art energy efficiency, as well as providing stunning and optimized graphics rendering with the support of the 2.5D NeoChrom Accelerator, Chrom-ART Accelerator, and Chrom-GRC™ MMU.

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, 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 STM32U5A9J-DK Discovery kit integrates 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.
