# Ledger Nano X board map: tracing and reconstructing the main board

> Ledger Nano X board map reconstructs the hardware wallet's main board from photos, tracing 40 test pads, copper nets and components into a KiCad project. Photo and 3D viewers expose the mapped connections, while scripts regenerate the board and schematic from the recorded data.

## Requirements & limits

- **Prerequisites:** Viewing the photo map requires a browser; regenerating the KiCad project requires KiCad 10 and its Python module.
- **Limits:** Inner layers are assumed, footprints are approximate, and signal names ending in ? remain unconfirmed.
- **License:** Code is MIT; photos, board data, the KiCad project and documentation are CC BY 4.0.
