I’m finalising the electronics for a high-end Smart RO water purifier and need a seasoned PCB designer to turn my requirements into production-ready hardware. The board must seamlessly handle water-quality detection while offering rock-solid Wi-Fi connectivity and an intuitive touch-control interface—those two features are non-negotiable. Alongside them, the design should accommodate auto-TDS control and an alkaline adjustment mode so users can fine-tune mineral content on demand. Sensor integration includes a TDS probe, temperature probe, flow sensor, and the drivers necessary for a mineral-mixing pump. All of this has to fit within a compact, appliance-friendly footprint and meet typical safety standards for domestic water equipment. Deliverables • Complete schematics and multilayer PCB layout (Gerber, drill, pick-and-place) • Well-structured BOM with part numbers available through major suppliers • Design files in Altium, KiCad or equivalent, plus exported manufacturing packages • Reference design for Wi-Fi module antenna placement and touch-button stack-up • Test points and firmware pinout documentation so my firmware team can plug in quickly Acceptance criteria: the prototypes pass bench tests for Wi-Fi range, touch sensitivity through the front panel, stable readings from all sensors, and reliable pump/valve actuation under continuous duty for 48 h. If you have proven experience with smart appliances or water-purification systems, I’d love to review your portfolio and timeline to get this board into fabrication.
