TouchGFX : How to Choose the Right STM32 Discovery Board

In this video, we talk about how to choose the right STM32 Discovery board for working with TouchGFX and building graphical interfaces. We look at several popular boards, explain their key features, and help you understand which one might fit your project best.
We cover the following Discovery Kits:

STM32U5G9J-DK2
Ultra-low-power MCU with Chrom-ART, NeoChrom accelerator, 4 MB Flash, 3 MB SRAM, and a 5-inch 800x480 capacitive TFT LCD. Ideal for power-efficient graphical applications.

STM32H747I-DISCO / STM32H747I-DISC1
Dual-core Cortex-M7 + Cortex-M4 MCU, MIPI-DSI display support (on the DISCO version), SDRAM, Quad-SPI Flash, audio, camera interface, and extensive expansion connectors.

STM32H735G-DK
A high-performance Cortex-M7 board with Ethernet, USB, SAI audio, HyperRAM, Octo-SPI Flash, and a 4.3-inch capacitive touchscreen. Great for complex applications with higher processing requirements.


STM32U5x9J Discovery Kit (STM32U5G9J-DK1 / STM32U5A9J-DK)
Features the new NeoChrom VG GPU, designed for smooth vector graphics and animations. Includes a 2.47-inch 480x480 round MIPI DSI LCD, gesture sensor, eMMC, PSRAM, and multiple expansion connectors for prototyping.

STM32F429 Discovery
Beginner-friendly board with a 2.4-inch TFT LCD, external SDRAM, USB OTG, and a MEMS gyroscope. A great starting point to learn TouchGFX and display handling.
