@rvwebfreelancing

Hi there! We can design a custom multi-port PoE Ethernet switch with schematic capture, PCB layout, power distribution, and production-ready files optimized for reliable network performance. A robust PoE switch design requires careful power budgeting, signal integrity, thermal management, and compliance with IEEE PoE standards to ensure stable operation and manufacturability. Questions ✅ How many PoE ports are required, and which PoE standard should be supported (802.3af/at/bt)? ✅ Do you already have a preferred switch chipset and schematic, or should the hardware be designed from scratch? ✅ Do you require Gerber files only, or also schematics, BOM, PCB source files, firmware support, and 3D enclosure integration? Check portfolio: www.freelancer.com/u/rvwebfreelancing/mech We will answer all questions and ensure a professional, smooth project process. Ready to begin. Buildtrix Studio

Drawing from my broad and deep expertise in Electrical Engineering and Embedded Systems, I believe I am the ideal candidate to design and deliver your customized 6-port PoE Ethernet Switch. Your requirement for delivering 70W of IEEE-compliant PoE across three channels, along with the other stringent electrical demands necessitate a creative thinker and skilled engineer like myself. I have a wealth of experience designing high-power PoE solutions, and working with custom connector configurations - precisely what your project mandates.

@crauch66

Hello, Client. I read your requirements carefully and understand that the key challenge is not only creating a 6-port gigabit Ethernet switch, but also making 3 ports deliver up to 70W IEEE-compliant PoE, 3 ports deliver 20W, and routing every data plus power line through JST-GH connectors in a compact, production-ready PCB. I can design the complete hardware from concept to release files, including switch IC selection, PoE PSE controller design, 10-26V to 50V DC-DC power stage, magnetics, reverse polarity, surge and hot-swap protection, impedance-controlled PCB layout, thermal planning, BOM, register bring-up scripts, and test documentation. Plan: 1. Review reference products, port requirements, size limits, and power budget. 2. Select switch silicon, PoE controllers, DC-DC topology, magnetics, and JST-GH pinout. 3. Create schematic and review with you before PCB layout. 4. Design multi-layer PCB with impedance control and thermal relief. 5. Prepare BOM, sourcing notes, register setup, bring-up guide, and test plan. Estimated timeline: 2-3 weeks for schematic, PCB, BOM, documentation, and review iterations. I have strong experience in PCB design, embedded hardware, power electronics, protection circuits, firmware, testing, and production-ready documentation.

@lewisd7

Let's build this together—I'll convert your 6-port Gigabit PoE concept into a production-ready hardware package: compact 4-hole M3 corner mechanicals, true GbE switching with VLAN/QoS, and two PoE tiers (3 ports up to 70 W, 3 ports up to 20 W). PoE out will be 50 V, powered from 10–26 V with essential protection for reverse polarity, surge, and hot-swap events. I’ll adapt the magnetics/PHY interface so each data+power pair exits via JST-GH connectors as requested. You’ll get full deliverables: complete schematics covering the switching IC, PoE PSE controllers, DC-DC stages, magnetics, and protection; a multi-layer PCB layout with impedance control, thermal relief for the power path, and the exact front-panel JST-GH footprint. I’ll provide a fully populated BOM with sourcing notes, plus firmware/register scripts to initialize the switch silicon and enable PSE modes.
