Yahboom MCU RCT6 Development Board STM32 Experimental Board ARM System Core Board 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 10 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. RCT6RET6 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 simulat
