PCB Redesign for Added Functionality

I need an experienced PCB designer to take an existing board and re-engineer it so it can do more without complicating assembly. My main goal is increased functionality, but I still want the layout to rely on through-hole components because that matches our current production line and simplifies repair work later. The board will live in a strictly indoor setting, so ruggedization for weather is not a concern. You will start from my current schematic and Gerber set (I’ll share them once we agree to proceed) and add the new features we discuss while keeping trace integrity, clearance rules, and component spacing in check. Please feel free to suggest additional input/output ports, wireless modules, or smarter power-management sections if you see clear opportunities; I’m open to ideas as long as the core through-hole approach remains intact. Key expectations • Update schematic and PCB layout in Altium, KiCad, or a comparable professional tool • Provide manufacturing-ready Gerbers, drill files, updated BOM, and annotated assembly drawings • Ensure all new functions are validated with basic signal-integrity checks and DRC passes • Deliver the project files so my team can continue iterating internally If you have a track record of squeezing extra capability out of legacy designs while respecting through-hole constraints, let’s talk.
