6-Layer Plating Gold! STM32F103C8T6 Minimum System Board

Overview

The main controller is an STM32F103C8T6 six-layer board . The signal-ground-signal-power-ground-signal
configuration includes a Type-C power supply interface (LDO) of 5V-3.3V , one power indicator LED, one SW programming indicator LED, two LEDs connected to the microcontroller's GPIO, and two buttons connected to the microcontroller's GPIO pins. All GPIO pins are brought out, with a 17mm distance between the pin headers on both sides.
