Custom ESP32-S3 Controller PCB
Budget: €250 – €750 EUR
I need an experienced KiCad 8.x designer to turn my FS-CTRL-1P controller concept into a production-ready board for JLCPCB. The design combines an ESP32-S3 MCU with Ethernet (W5500 + PoE), Wi-Fi, 4G LTE via Quectel BG95-M3 (dual nano-SIM), RS-485/Wiegand on a shared terminal, two SPDT relays, three opto-isolated inputs, a Li-Po charger (TP4056), a hardware watchdog (TPL5010) and a remote I²C header for an OLED display. All field connections terminate on pluggable blocks.
What I need from you
• Review my specification PDF in detail—BOM, GPIO table and electrical constraints are top priority.
• Capture or verify the schematic and complete the PCB layout, keeping to the size, power and thermal guidelines in the document.
• Follow manufacturer-specific guidelines: JLCPCB DFM rules, an LCSC stock check for every part, and reference layouts for the ESP32-S3 and BG95-M3.
• Deliver a clean manufacturing package: Gerber, BOM with LCSC numbers, and CPL files ready for turnkey PCBA at JLCPCB.
• Provide an estimated timeline and fixed quote after you review the spec.
I’m happy to answer technical questions quickly so you can move fast. Looking forward to your expertise on this build.
