With SWD simulation debugging download interface, compared with traditional JTAG debugging, it is more reliable in high-speed mode, and the probability of download failure is smaller9. Immersion gold technology, small size, reasonable and standardized layout and routing, high-quality SMD crystal oscillator, high quality10. Using the Type-C interface, it can be used for power supply, program download and serial communication11. C8T6 is equipped with high-quality 1x20 pin headers to ensure firm contact. At the same time, it adopts half-hole technology to facilitate customers to solder leads12. RCT6/RET6 is equipped with high-quality 2x15 pin headers to ensure firm contact, and can be placed on a universal board or breadboard according to requirements13. Reserve SWD debugging interface, support J-link, ST-link simulation online debugging code14. The onboard 8P FPC connector supports the connection of a 0.96-inch TFT color display, which can be used to display Chinese characters, character strings, and pictures15.
