Currently seeking an electronics engineer to design a custom circuit / PCB based on a working Arduino PID controller prototype. (MCU programming is not part of this solicitation but may be involved in follow-up work.)
Budget negotiable based on experience & expertise.
Size: Approximately 5cm x 5cm, 1 or 2 Layer
Input Power: 120VAC @ 60Hz
The device will have various inputs and outputs (buttons, sensor, buzzer, LEDs, etc.) that will be PCB-mounted and/or attached via PCB-mounted connector. It will need to have an integrated power supply as well as a solid state relay circuit (opto-isolator / triac) for controlling a separate mains-powered device. It should also include safety features common and/or required (UL, CE or otherwise) for use by consumers.
The design must follow best practices and be verified by common rule checks. Deliverables include a complete technical specification (gerber files, schematics, design files) and a detailed BOM outlining the most...
