Request for quotation – ultra-compact custom PCB design with ESP32 and DC power supply

Job ID: 39550868

Budget: €30 – €250 EUR

Hello,
I am looking for a professional to design a custom PCB (no firmware development required). The requirements are:
• ESP32 (with boot/reset buttons)
• USB-C port for power supply and firmware programming (PlatformIO)
• DC power input (range 3.3–36V)
• Ethernet port with PoE (Power over Ethernet) support
• Adjustable DC output (using a trimmer or similar, to power external devices from 3.3V to 36V)
• 2 ultra-compact relays, controlled by the ESP32 and opto-isolated
• 2 inputs for Wiegand readers
• Socket for future connection of a GPIO expander

The PCB design must be ultra-compact.

I need:
• Schematics and Gerber files ready for manufacturing
• Complete Bill of Materials (BOM)
• Possible support for prototyping

I do not want automatic or bot-generated offers. Only genuine proposals based on my specifications will be considered. I will not accept later negotiations or price changes.

The firmware will be developed by myself.
Please include estimated timeline, total cost, and number of included revisions.
Thank you.

Best regards,
Luca
