ESP32 Triple-Camera PCB Design

I need a compact PCB that lets one ESP32 talk to three OV5640 cameras, one at a time, then push the captured frames out over Wi-Fi. The board must handle all hardware multiplexing so the microcontroller can switch between the sensors sequentially under firmware control.

Key elements I expect:
• Schematic and layout (Gerber/ODB++ ready) showing the camera ports, MIPI or parallel routing as required, level shifting, power rails, clock distribution and the multiplex logic you select (FPC switch, analog switch, or similar).
• A clear BOM with part numbers that are current and readily available.
• Pin map and any required initialization timing so I can drive the switch from ESP32 GPIO.
• Brief test firmware (ESP-IDF or Arduino core) that cycles through Cam1 → Cam2 → Cam3, grabs a frame from each and streams it out via Wi-Fi, proving the routing is sound.

If you’ve built high-speed camera boards or worked with the OV5640 before, let me see an example—signal-integrity insight is important here. I’ll review the design in Altium, KiCad, or Eagle, whichever you prefer, but please include the standard output files so I can send the board straight to fabrication.
