Jiujiu boot stick 1.0&esp32 weather clock 1.0

The project contains three PCB files, one is a boot stick inserted into the 9-pin switch interface of the computer (the idea is to store the weak current of the 9-pin interface without external power supply and provide it for short-term operation of low-power Bluetooth). Now The hardware debugging has been completed, and the software has not been written yet. This is it for now. The source program will be uploaded after the program is written. A bug in the circuit was corrected. PS: I am ready to give up the solution of not using external power supply. The leakage of the circuit and the capacitor is a bit large. This 0.47F capacitor can only last for 3-4 hours after shutting down, which does not meet the requirements at all.

The other is an esp32 weather clock (displayed with an e-peaper [ink screen]) that can be placed on the desktop or carried with you. It is also a remote control used to control power on and off and reset. PS: Although the welding has been completed, During debugging, I plugged in the screen and found that the order of the screen cables was reversed, and the RXD and TXD used for downloading were reversed. The modified version is already on the way to express delivery. In addition, the modified version also draws all the lines on the board with arcs. The whole page routing looks very soft (probably not useful). The modification permission is temporarily open for one day, so I will give some instructions and attach the half-assembled look. After that, the finished product will only be released in the comment area.

Below is a picture of the actual object after welding

After assembling half of the shell

The third one is a casing made for the esp32 weather clock with every layer from the front panel to the back panel.

I have uploaded the Lichuang eda project file, uploaded pcd_gerber, and the pcb_gerber of the shell. However, it has not been uploaded. Please divide all panel layers into independent PCBs one by one to generate gerber. Special note: There will be errors in the panel file, but since it is just a shell network and DRC error, it can be ignored.
