Suggestions for MCU Choice

2fourK · ‎2025-02-25

Hi :waving_hand:,

I am designing a midi controller. I want test out using an STM30 MCU, I was wondering if anyone could suggest dev board/ processor?

I don't want or need wireless communication (wifi and Bluetooth)

I want to run a lot of linier potentiometers/ fader / lingering encoders. Using usb C

In whish list for final product I want to have USB C throughout for data,

My primary design constraint is that I want final production units to cost no more then $100.

So I want to find right MCU that is cost effective for fader inputs with out bells and whistles.

Thanks for you help,

Jim

Hi @2fourK

I recommend taking a look at How to write your question to maximize your chance... - STMicroelectronics Community

First, you can refer to the STM32H7RS line with bootflash. Here where you can find the software and hardware tools available:

Nucleo board: NUCLEO-H7S3L8
Discovery kit: STM32H7S78-DK
Dedicated software package: STM32CubeH7RS
X-CUBE-TOUCHGFX board support package in TouchGFX Designer
Expansion packages such as X-CUBE-AWS-H7S, X-CUBE-AZURE-H7S, X-CUBE-AZRT-H7RS
