Altium PCB Design for DSLR Camera Trigger

Project Title: Design a Raspberry Pi HAT PCB for DSLR Camera Trigger - Altium

Project Description:
I need a small PCB designed that sits between a Raspberry Pi and a DSLR camera to trigger the shutter and focus.

Requirements:
- 3x Female GPIO Headers to mount directly on top of Raspberry Pi
- 2x Optocouplers to separately trigger Camera Focus and Shutter
- 2x Resistors for current limiting
- 1x 2.5mm TRS Jack for camera connection
- All components must be Through-Hole for easy home soldering. No SMD
- All parts must be available from UK suppliers like RS Components or Farnell
- PCB should be compact and designed as a Pi HAT

Reference:
Google "Corona designs Raspberry Pi DSLR camera trigger" - I want the same but with 2 optocouplers instead of 1

Deliverables:
1. Complete Altium Designer Project Files: .PrjPCB, .SchDoc, .PcbDoc
2. Production Ready Gerber Files + Drill Files
3. BOM with RS Components / Farnell Part Numbers
4. PDF Schematic

Notes:
- I will provide the exact GPIO pins and Camera model after project start
- I only need the PCB design. No coding or manufacturing needed.
