This is a small development board using the STC8G1K08 chip.
STC8G is STC's latest series of chips. It does not require an external crystal oscillator or external reset microcontroller. What's even more powerful is that it supports USB direct download, and even the serial port chip can be omitted. When I was studying in the past, the teacher also taught me "the minimum microcontroller". No matter how the system is designed, the current microcontroller can be used when it is powered on. It is too powerful.
First, refer to the STC8g user manual to design the core part of the board: microcontroller + USB download + one-click power off
Then design the peripheral components of the development board. Since it is a development board, it must be used to learn peripheral components, such as common LED lights, button extensions, relays, OLEDs, LCDs, etc.
That's it.
