STC8H8K64U development board

# STC8H8K64U Development Board

## Preface This

  is a development board based on STC8H8K64U open chip design. I drew this some time ago. At that time, I wanted to learn STC8H, but I didn’t have a development board based on this chip, so I wanted to draw one. However, after the board was welded and it was verified that the automatic download was OK, I didn't use it because I had to learn other microcontrollers.

## Circuit

> The following is the draft plan at that time. I don’t know exactly how many functions were installed. Because I want to make a smaller board and modify or delete some circuits.

> The schematic diagram is the existing circuit module, and it is clearly marked.

## Draw

> As the saying goes , the technology is not enough, so I can make it up by drawing. Some small patterns were drawn on the development board.
>
> I drew a little-looking Cairo Junha, and the Cairo game is great.

## Actual object

> There are still some components that haven’t been soldered yet, so I didn’t buy it at that time. After verifying that the automatic download can be used, it was in vain.

## Finally

  , in general, the drawing of this first board (V1.0) was a little rushed. I originally wanted to at least finish some of the back of the PCB first. The silk screen of the items was done first, as it seemed that there was not much space, and then I didn’t have much time, so I just printed the screen. Also, people are stupid. When they light up the lamp, they find that it is at a high level. Usually it is at a low level. Obsessive-compulsive disorder sets in. Maybe they were stupid at that time.
