Other key parts include the CS32F031K8V6, ZB 25VQ32, TP4054 and LDO. By type, the board carries 15 resistors, 7 capacitors, 5 transistors, 4 ICs, 3 connectors and 1 fuse.

It belongs with the displays & leds designs in this gallery.

From the project

Reverse engineered disposable v a p e boards

Disposable vapes show up all the time in e-waste and are often found as litter at the side of the road (shame!) but they contain some useful components that can be reused by the cost-conscious hacker.

Note: Wear gloves when handling used devices and don't allow the vape liquid to contact your skin or eyes.

I've reverse engineered a number of different brands and placed the schematics and layout files in this repository. The summary table below is a good starting point.
