TYPEC to DC interface

The problem requires
a dedicated decoy for ultra-cost-effective soldering irons. It is extremely low-cost and addresses the shortcomings of commercially available decoys, which are often too long. This decoy for ultra-cost-effective soldering irons perfectly matches the existing high-performance soldering irons and fills the power supply gap.
Analysis:
Because many commercially available decoys are too long, making the soldering iron unusable and somewhat heavy, this shorter decoy was designed. The principle is very simple, making it easy to replicate. It only requires a simple CH224K chip to function properly.
Schematic Design Explanation:
Using a CH224K chip... The principle of using a decoy to output voltage to the DC interface and then power the appliance is extremely simple. Only two indicator lights are used for display, making it relatively easy to replicate. The principle is also relatively simple; it can be completed with approximately 20 components, and the overall cost is less than 5 yuan. Soldering is also relatively simple.

precautions are
all provided. **Important Note:** The length of the DC interface must be trimmed after soldering, otherwise it may short-circuit with the second board, causing a serious problem. Remember to remove any excess spring contacts after soldering.
