From the project
Complete project for the Airbus A319/320/321/330 OverHead Panel
The v2 board under the EXT LT panel. It carries the panel's switches, annunciator LEDs and backlight, at their v1 positions, and reaches the mainboard through one ribbon and one pair of backlight wires. There are no ICs on it. The design rules shared by the eight section boards are in docs/board-split.md.
PCB: 159.5 × 79.5 mm, 2 layers, 1.6 mm. Every v1 hole is kept. Status: routed with Freerouting. ERC, DRC and schematic parity are clean. Not yet ordered.
