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.
