The multi-module expansion board 3.0 can realize automatic downloading and programming. The pins of each module have been lead out. Note: VCC and GND are connected to each module. In order to reduce the size of the board, they are not lead out separately!

Creators of the CH340C/G chip in the board can choose one of them. The CH340G crystal oscillator pad and 22PF capacitor pad are reserved on the board. With CH340C, the crystal oscillator and 22PF capacitor can be omitted!

The problem with the test pins in the board is that the ones from Xinbao are too expensive. It would be too expensive and not cost-effective to buy the entire board from Xinbao. So I have always made them by myself, but it is very time-consuming and labor-intensive, but I have plenty of time, haha. ! It takes more than half a day to make a neat finished product, even without rest! So if you want to save money, you have to spend time and energy! You can't have your cake and eat it too!

Since I don’t have such a complete list as the above, I haven’t verified it one by one. However, after comparing the parameters in the specification manual, it is theoretically supported. So if you have any modules that fail the test, please correct me! If you have any better suggestions or ideas, you can leave a message in the comment area or send a private message!

The above is the introduction of the PCB board, and the next is the introduction of the 3D shell. When Lichuang first started the professional version, Lichuang gave away 3D printing coupons, so I was also one of the first users to use the professional version of Lichuang, so I printed the shell once. Since I had no experience for the first time, I didn’t draw the size very well. I took the hand board and put it in. The USB port and DIP switch were not very suitable. Since I didn’t catch up with the free opportunity later and the shell size exceeded the free proofing specifications ( It was only about 5mm larger, so I didn’t print the shell anymore! (I’m not a wealthy person). The EDA professional version also has the 3D shell I drew. If it needs to be printed, I need to design it carefully!

I also have the finished product of a certain fish, if you are interested you can check it out!

Any suggestions and requests accepted!
