SRL I’ve reviewed the requirement for a production-ready ESP32-based carwash kiosk controller with HUB75 output and 9-36V input. I’ll design a robust, industrial-grade PCB with reverse-polarity and transient protection, ESD protection, and outdoor reliability for −20°C to +60°C. The design will include 10 independent outputs with timed control, synchronized with a P10 display timer, and flexible Pulse+/Pulse− inputs (dry contact or opto-isolated). I’ll select components with reliable, mass-production supply paths (Özdisan where possible), deliver Altium-ready schematics and layout, Gerber files, BOM, P&P files, and manufacturing docs. What is the expected maximum pulse rate and duty cycle for each input channel, and are there any constraints on the LED panel driving current or PFC requirements for the 9–36V input? Best regards, Marko Aleksic

SRL Hi, I'm experienced PCB designer and have designed multiple industrial grade products that are still deployed and working well in the field. Some examples include Raspberry pi based IO boards. I can show you 3D models if you want to see. I work with a company in US and they have full manufacturing facility which provided me valuable experience with production related constraints and requirements. For your product, I think ESP32 will be enough to handle everything. It will be deployed in a car wash so it will require to be temperature, vibration and moisture resistant. Do you have any certifications in your mind to this product certified? As you already specified, Deliverables will include schematics, PCB layout, Gerber files, BOM, Pick & Place files, and basic manufacturing documentation. My estimate for this project is one week and 1200 USD. Open for negotiation for timeline and cost. Let's discuss further details about product price and timeline.
