Super capacitor voltage equalization

Some time ago, I was very fascinated by supercapacitors. I bought a bunch of supercapacitors and copied a supercapacitor voltage equalizing plate based on TL431 online. The balancing voltage can be adjusted by yourself according to the formula. The minimum balancing voltage is 2.5v, and the balancing voltage of this project is 2.65. In order to facilitate the design into an independent structure, the middle pad is a connecting piece. You can cut it by yourself and it can be parallel or stringed. The size is 40*96. If you don't mind the trouble, you can add two more to the existing circuit board to smooth out the wool to the extreme. But be careful not to simply copy and paste on the PCB drawing, otherwise it will be judged as a puzzle by Lichuang. Boards and wool can’t be rolled out, hahahaha. You need to copy and paste from the schematic diagram, update the component number and then redraw the pcb yourself.
