【GD32307E-START】03- Schematic diagram of expansion board [Copy link]

Since I am in the industrial control industry, I basically work on RS485 interfaces and network ports. When I designed the schematic, I expanded the 485 interface, 2 CAN interfaces, 1 Ethernet interface (RMII), and an IIC 0.96-inch OLED interface, plus SPI-Flash. The test chip should be similar. I put the schematic below. Please give me some advice. There may be something wrong with the schematic. I hope you can point it out.
