#The 5th Lichuang Electronic Design Competition#32-bit MCU development board

Note: * is a required field.

[Please fill in during the registration phase↓]
* 1. Self/Team Introduction
I mainly work on hardware: 1. Switching power supply design, flyback switching power supply, dual-tube forward, etc.
                          2. LED lamp design, including dimming and color adjustment.
                        3. Digital circuits are designed according to product needs. The main focus is on 32-bit microcontrollers. Occasionally, FPGA is also involved.
* 2. Briefly introduce the project
 The product designed this time is mainly low-cost and stable. This time, the 32F107VCT6 was tried. This board is suitable for stm32 and GD32.
Product features: 1. Low cost
                2. Can connect to high-speed USB and support hot plugging.
               3. External 10~100M network card.
              4. Dual CAN.
             5. Two current detection. The highest DC voltage can be directly detected is 310V.
            6. A relatively complete plane ground, which can be used for product use with little modification.
           7. Secondary development is possible, and there is still some space.
