STM32H747AI

[balogandrej9184]

Hello,

I am relatively new here and would like to try to design a STM32H747AI board with LiPo battery power supply for wearable devices with features like OLED microdisplay, WiFi+Bluetooth and GNSS module. Since I would like to run a GUI on it with smooth 2D and 3D animations, what RAM should I use? What is the maximum RAM data bus width, size and speed supported by MCU? Also, how can I connect the eMMC to the MCU and what speed mode should I use if the datasheet states a maximum of 125 MHz? And how can an OLED display be connected to the MCU and what is the maximum resolution at which the display can operate at 60 fps (alternatively 30 fps) ? I searched the datasheet for answers, but didn't find the answer I was looking for, or I just wasn't sure.

Thank you very much in advance for any advice.

Regards

Consider using a dev board as a starting point. Schematics and examples are available. Going to be hard to pull off all of that on a first board without relevant experience.
