Arknights Rhode Island theme decorative lamp touch adjustment USB power supply 8022W

The proofing has been verified, and a small problem has been fixed (the keychain hole position was GND before, and after changing to button battery power supply, the keychain is prone to short circuit with the positive pole of the battery, which has been corrected).
The touch area pattern is open window. For your health, it is recommended to use lead-free tin spraying or immersion gold process (or change the window to silk screen). However, if you are a freeloader like me, then it is another
8022W control chip, which is very common. For detailed instructions, please refer to the chip manual.
Use 38mm long LED light strips, just search for ceramic filaments on tb, the rated voltage is 3V, and the color depends on your preference.
It is recommended to use 33nF sampling capacitors, 10nF is prone to touch insensitivity, if it is changed to buttons Battery powered, using 10nF touch function will be extremely insensitive.
It is not recommended to work at the highest brightness for a long time. The heat is large. The filament has poor heat dissipation.
Low brightness may trigger the low-load sleep of the power bank. Please note
the following pictures:
The highest brightness is still quite bright
 
. There are three types of PCBs, namely Type-c version, pendant version (cancel Type-c protrusion, add two windows to facilitate battery welding, voltage is at your discretion), pure pendant no circuit version (cancel Type-c protrusion, retain slots, cancel all circuits, this version has less decoration on the back, if you think it is not beautiful enough, add it as appropriate)
 
Change to button battery power supply as a keychain Notes:
1. It is not recommended to work at a high brightness. It is only recommended to work at the lowest brightness as a decoration. We are not responsible for any damage caused by excessive current and battery heating caused by long-term high brightness.
2. Do a good job of insulation.
3. The copper plating of the TOUCH part can be made smaller to reduce false touches.
4. Without rigorous measurement and calculation, a CR2032 battery has a standby time (without turning on the light) of about half a year and works for about 100 hours at the lowest brightness.
5. No space is reserved for button batteries. Please feel free to use your imagination in placement and wiring
 
. The base is being made using polymer lithium batteries and TP5400 solution.
