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.
