Dragon Slayer Saber Third Generation Reissue

This project is a replica of the STC official Dragon Slayer 3rd Generation development board. The chip options are STC32G12K128-LQFP64 or STC8H8K64U-45MHz-LQFP64.
I. Images of the Dragon Slayer 3rd Generation board
; II. 3D demonstration of the development board;
III. Onboard functions:

All chip pins are brought out (H3 and H4 are soldered to header pins).
The onboard LQFP64 chip is converted to DIP64 for outgoing pins (H1 and H2 are soldered to header pins).
All I/O ports have LED indicators (common anode, with current-limiting resistors).
When the LQFP64 chip is not soldered and H1 and H2 are soldered to header pins, a DIP64 interface can be used. The core board
has an anti-static USB Type-C interface that supports downloading and a download button (OFF and S3 buttons) that allows data cable unplugging.
It supports STC USB-Link1 (J4) and STC USB-Link1D (J2+J4). The emulation tool
chip can be selected as 5V or 3.3V, and a 3.3V emulation tool is also available onboard. LDO voltage regulator chip
with 5V power output; when using 3.3V, the 5V power
supply can be used simultaneously. Onboard reset button.
Onboard four programmable buttons (requires internal pull-up, low level when pressed).
Onboard one five-way multi-function switch (joystick - no linear function) (requires internal pull-up, low level when pressed).
Supports AC or DC signal input to the ADC via a 2.54mm pitch XH 2-pin interface (J5, short J6 to test DC, not shorted to test AC).
2.54mm pitch XH 3-pin external CAN bus interface .
2.54mm pitch XH 3-pin external LIN bus interface.
Onboard TJA1050 CAN bus chip (can test CAN transceiver function on the same board when both are soldered).
Onboard independent LIN bus chip supporting external power supply (can test LIN transceiver function simultaneously when both are soldered).
Onboard three PWM DAC conversion circuits, two with second-order RC filters and one with an LC filter. Onboard
circuit board for testing UART transceiver function.
Onboard 7-pin 2.54mm pitch SPI protocol display interface, also compatible with 4-pin... The I2C protocol display
board features an onboard 431 external voltage reference circuit
and an NTC temperature measurement circuit.
