Precautions

• Due is a special product. There are not many Due compatible shields currently known, mainly due to the differences in class libraries. The pin definitions of Due and Arduino MEGA 2560 are exactly the same, but the power supply parameters of the I/O ports are different. Different, the Arduino Due official website has a warning:
  
• ------The store has carried out strict tests on each Due before delivery. Please read the relevant instructions and documents on the official website of Due carefully before use. The store is not responsible for any damage to the Due due to improper operation.
• If you need to know more about the solution of Due related problems, you can search the official forum:
• ------The wrong USB download port is selected, pay attention to check the Ard 1.5.x software, select the download port in the menu bar Board that matches the actual connection of the USB cable to the Due
