Microcontroller learning board based on STC8A8K64S4A12

Overview

The introduction of the microcontroller core board based on STC8A8K64S4A12 is as follows:

1. It uses micro USB 5V power supply, the AMS1117 linear regulator steps down to 3.3V, and has a USB to TTL interface composed of CH340E;
2. It has an external crystal oscillator circuit and an external reset circuit, and the user You can choose whether to use it;
3. It has a Boot button, through which you can start downloading;
4. It has a high-precision 2.5V reference source, which divides the analog ground and digital ground to provide an accurate reference source for the analog port, such as ADC etc.;
5. With 2-way Led, 2-way Key, oled display (I2C), expandable esp01s;
6. I/O is led out through the expansion port;
7. The controller adopts the LQFP-64 package type STC8A8K64S4A12, with full overall dimensions It is 5*5cm.
