8A8K core module (with automatic download)

Overview

This project uses the smallest system board (with automatic download) made by STC8a8k microcontroller. All pins are lead out, and the interface of the SPI protocol OLED display and five buttons are reserved (P5.4 can be used as a reset button It can also be used for IO) ![Pin.png]
