Yahboom MCU RCT6 Development Board STM32 Experimental Board ARM System Core Board, Specification: STM32F103RCT6
- 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
- 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.
- STM32F103RCT6: Contains all the pins of STM32F103C8T6 and some other peripheral pins, which can directly use the STM32 large-capacity standard library
- 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
- 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
- The core board leads to all 1/0 port resources
- 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
- Immersion gold technology, small size, reasonable and standardized layout and routing, high-quality SMD crystal oscillator, high quality
