# STC32G12K128 Minimum System

### Preface:

This board was drawn a long time ago, and the overall use is 0805 chip resistors, capacitors, LEDs, etc. It's not a big project.

### Idea:

The overall production idea of ​​this core board:

Download: It adopts the STC manual without serial port chip download (after verifying the board, it is OK, but it is too troublesome. After each download, You have to press P32 and turn the power off again to download once. Moreover, it cannot communicate directly with the serial port, which is not very friendly for a novice like me.)

It leads to three module ports: 4POLED interface, NRF24L01 interface. ESP01S interface. (After board verification, it was found that because the size of the 0.96-inch OLED screen was not considered at the time, the other two interfaces would be blocked when the screen was placed.)


All the on-chip pins are lead out.

### Disadvantages:

After receiving the board and verifying it, I found the shortcomings. In addition to the above, there are also:

all the on-chip pins are lead out, but I forgot to lead out multiple external power supply ports.
