STM32 minimum system

Overview

MiniDev.Board Hardware Resource Description1
. Tested compatibility with the following MCUs:
        STM32F030C8T6
        STM32F103CBT6
        STM32F400CBT6
        PT32F030C8T6
        is also compatible with other manufacturers' MCUs such as GD32, AT32, etc.2

. Onboard LCD 0.96, ST7735 driver display, verified to be lit (test project will be placed in the attachment)

3. Onboard CH340N serial port, TypeC interface, up to 2M, verified4

. Onboard five LEDs (power, PC14, PC15, TX, RX) and two buttons (PC13, NRST)

5. Onboard SPI Flash, sharing SPI1 with LCD, not verified.

Note: Because I want to play the gold, so the luxury of using a 6-layer board, free is happy! ! !

PS: The power light and IO port lights are reversed on the back. This is a project based on a platform. I can no longer find the link to the post.
The attachment is a test LCD project based on STM32F400CBT6, compiled with KEIL, and the crystal oscillator is a 24MHz external crystal oscillator
