Smart Whirlpool Controller PCB Layout

I already have a fully working prototype of a smart control system for my whirlpool, complete with firmware. It manages temperature regulation, drives the water-jets and handles the LED lighting. What I now need is a production-ready printed circuit board that brings all of this together cleanly and reliably.

The core of the design is an MCU (currently an Arduino-class microcontroller) plus a handful of sensors. The firmware is stable, the pin-mapping is fixed, and the schematic is drawn—your task is to turn this into a compact, manufacturable PCB that I can send straight to fabrication.

You will receive:
• the current schematic in PDF and KiCad format
• the pin-out and footprint of the chosen microcontroller
• a list of the temperature and pressure sensors already tested with the code
• mechanical constraints of the housing inside the whirlpool control box

Please return:
• finished PCB layout files (KiCad preferred, Gerber + drill files mandatory)
• an up-to-date BOM with manufacturer part numbers
• fabrication notes (layer count, board thickness, copper weight, any special considerations)

The layout needs to respect safe mains/low-voltage separation, splash-proof connector positioning, and keep sensor signal paths clean for accurate readings. If you spot opportunities to improve reliability or reduce cost, I’m happy to hear suggestions as long as they stay compatible with the existing firmware.

Once I can load the Gerbers into the fab tool without errors and the board fits the enclosure drawing, the job is done. I’m ready to start immediately and can answer technical questions quickly.
