Product Description:
1. Using STM32F103RCT6 chip as the main control IC
2. With 72M main frequency, 256K FLASH, 48K SRAM
3. Equipped with interfaces such as IIC/SPI/CAN/UART/USB and peripherals such as DAC/ADC/DMA. Please refer to the IC parameter introduction or data manual for details
4. The development board has dual USB interfaces, one serving as an ISP download interface for downloading programs, and the other as a USB communication interface. (The USB communication interface requires the development of a USB communication protocol to be used. If a corresponding program is not developed, directly plugging in the computer will display that the device cannot be recognized.)
5. The onboard CH340C chip is used for USB to TTL communication, connected to serial port 1 of the main control chip, and also used for ISP burning
6. The SWD simulation interface can be simulated or burned, and emulators such as DAPLINK that support the M3 kernel can be used
7. TFT LCD screen interface, which can be used with our store's TFT LCD screen
8. Two 3.3V and 5V power supplies are led out each, either connected to one power supply or connected to a USB power cable development board to work. When connected to a 5V power supply or USB cable for power supply, the board can output a 3.3V power supply externally
