Prototypes have been made, and no bugs have been found during verification. If you encounter any problems, please discuss them below, thank you~
STC32G12K128 is the smallest system. The microcontroller is independently powered. All IOs are fan-out. USB direct connection for downloading. It comes with 3 sets of buttons + 2 sets of LEDs for easy debugging. It also comes with a second 3v3 channel for debugging.
The design with relatively simple functions makes it easy to use Dupont cables to connect peripherals for development and debugging.
USB download method: The minimum system is in a closed state. Press and hold the download button (SW4) and turn the switch to open the development board at the same time to enter the download state. The download operation can be performed through the STC-ISP software.
