Hi everyone, I'm working on an aftermarket Head-Up Display (HUD) system for vehicles, which taps into the OBD-II port and displays speed, RPM, and basic alerts on a transparent screen using a small projector. I'm currently prototyping the control PCB, which handles CAN communication, basic data filtering, and driving a compact display module. Since this will be installed on the dashboard area, I'm trying to factor in exposure to sunlight (heat), electrical noise from the vehicle, and the need for a compact layout. Has anyone here prototyped PCBs for in-car use, especially around noise filtering and thermal design? Any recommendations for layout techniques or materials at the prototyping stage would be a huge help.
