# Quansheng UV-K5 Hardware Reverse Engineering Project: V1.4 radio PCB reconstruction

> The Quansheng UV-K5 Hardware Reverse Engineering Project reconstructs the radio's V1.4 PCB as KiCad schematic and board files. The author describes measuring removed components, photographing and sanding the board to expose inner layers, and aligning those images while tracing connections.

## Requirements & limits

- **Prerequisites:** KiCad is needed to inspect or edit the schematic and PCB design.
- **Limits:** The board files require changes before manufacturing; the author lists value errors and incomplete 3D models.
- **License:** Hardware design files use CERN-OHL-S-2.0; documentation uses CC BY-SA 4.0.
