1. STM32F103C8T6: It is a model with a high market share in the single-chip microcomputer market, and is widely used in electronic design competitions, smart cars, robots, flight control, industrial control and other fields 2. GD32F103C8T6: It is a domestic alternative to STM32F103C8T6. The peripheral pins are exactly the same as 3. STM32F103C8T6. It is equipped with a new generation of Cortex M3 core, with higher CPU frequency, lower power consumption and higher cost performance. 4. STM32F103RCT6: Contains all the pins of STM32F103C8T6 and some other peripheral pins, which can directly use the STM32 large-capacity standard library 5. APM32E103RET6 is a domestic alternative to STM32F103RCT6. It has a higher main frequency clock and lower operating power consumption. The built-in flash is 2 times that of RCT6, and the SRAM is 2.7 times that of RCT6. It is more cost-effective 6. The board is equipped with STM32 small system circuit, among which STM32F103RCT6 and APM32E103RET6 are also equipped with a 6-axis IMU on board, which can be used to obtain motion attitude 7. The core board leads to all 1/0 port resources 8. 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 smaller 9. Immersion gold technology, small size, reasonable and standardized layout and routing, high-quality SMD crystal oscillator, high quality 10. Using the Type-C interface, it can be used for power supply, program download and serial communication 11. 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 leads 12. 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 requirements 13. Reserve SWD debugging interface, support J-link, ST-link simulation online debugging code 14. 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 pictures 15.
