Martin ROGER / VXDash - History

Minor PR updates

- Updated revision number in schematic
- Minor change of track layout to avoid ground island
- DRC OK and ERC OK
- Removed stale notes from schematic
- Updated PCB silkscreen

Preliminary circuit and PCB placement

Simple circuit to power a self-driven buzzer when the lights are on, ignition off and door open.

OpAmp reversal corrected + LTSpice

- Need to relayout PCB
- OpAmp LT Spice model

BOM first pass

- Still missing some internal connectors definitions
- Alternative to use a 4x4ch opto config instead of 16x1 ?
- Alternative LiteOn optos identified (easier to source on LCSC)

ERC corrections, idiot lights

- VXDash : added idiot lights (also to emulator board)
- VXDash : corrected some ERC violations

PCB layout in progress

Changed some pin assignments to aid routing.
