ESP32 HUD Prototype Refinement

I have an early-stage ESP32 heads-up display that boots and runs a demo, yet the hardware still feels like a proof-of-concept. My next step is to polish the design so it’s ready for a short production run.

The priority is the hardware design itself: re-working the circuit layout, tightening up component selection, and creating a proper enclosure. You’ll start with my existing Eagle files and 3D CAD, power up the current board to spot weaknesses, then apply the fixes that make the unit smaller, cleaner, and more robust.

Deliverables
• Updated Eagle schematic and PCB layout optimized for space and clean routing
• Revised BOM highlighting any component improvements or substitutions
• Manufacturable 3D enclosure model (STEP/SolidWorks/Fusion 360) that fits the new PCB
• Brief test report confirming the updated board boots, connects, and drives the HUD display glitch-free

If you also see opportunities for lower power draw or better signal integrity while working on the layout, let me know—those suggestions are welcome even though the main brief is the physical design. Please share a glimpse of similar boards you’ve taken from prototype to production and your primary CAD toolchain when you reply.
