STC8A8K64S4A12 LQFP64 development board

STC8A8K64 LQFP64 The difference between the integrated serial port minimum system using typec interface and other minimum systems

• Reverse connection protection
• Integrated serial port without compromise
• Using typeC interface for power supply and programming, supports forward and reverse insertion   (Don’t use mini, micro, typeb if it’s 0202)
• Ultra-low cost implementation of two-way DAC
• External 431 reference, supports jumper switch to 2.5V or 3.3V reference
• Onboard GND VCC SCL SDA interface OLED plug and play
• Using 3225 package 32MHz high-speed crystal oscillator, taking into account both size and cost.(8M is too expensive)
• TX RX independent indicator light.
• There are 3 LEDs and two buttons on the board, and KEY1 is connected to an external interrupt.
• One-click power-on of the entire board
• Self-created TI style library function support (currently the writing of clock configuration GPIO serial port has been completed)
• 32MHz current is less than 15ma

The board has been verified and the bugs in the first version have been fixed.
