Your project matches my expertise in KiCad, STM32, and multi-layer embedded PCB design. I have experience with RF layouts, low-power systems, impedance-controlled routing, and preparing production-ready files for JLCPCB and PCBWay. I can deliver the complete KiCad project, including schematics, 4–6 layer PCB, DRC-clean layout, Gerbers, BOM, CPL, and manufacturing documentation while following your milestone-based workflow. Before starting, I would like to confirm the preferred PCB stack-up, target impedance values, and whether Qorvo’s UWB layout guidelines and reference design files will be provided.

@yaroslavmark

Hi, I have 10+ years of experience in embedded hardware, RF PCB design, and firmware development, with 25+ custom multilayer PCB projects and 20+ four-layer production boards delivered using KiCad and Altium. I have designed low-power STM32 systems, RF interfaces, power management, and impedance-controlled layouts, including BLE, LoRa, Wi-Fi, and GNSS products, while improving signal integrity and reducing EMI issues in production hardware. Approach ✅ I will capture the complete KiCad schematic, verify every interface, power domain, and pin mapping, then review the architecture before PCB layout. ✅ I will define a 4-6 layer stack-up, optimize RF partitioning, controlled-impedance routing, grounding, shielding, and thermal isolation for the MAX30205 sensor. ✅ I will complete routing with DFM-compliant rules, optimize BGA fan-out, validate DRC/ERC, and generate manufacturing-ready Gerber, BOM, CPL, and assembly files. Questions ✅ I would like to confirm whether Qorvo provides the complete QM35825 reference layout, stack-up, and impedance requirements for the dual UWB antennas. ✅ Will the Swarm M138 breakout remain as a module on the PCB, or should it be redesigned as a native circuit? ✅ Do you already have a mechanical enclosure with fixed PCB dimensions, antenna locations, and keep-out zones for RF optimization? Best, Yaroslav

Hi I am an embedded systems engineer with over 16 years of experience. I have extensive experience designing multilayer, ultra-low-power MCU products with mixed RF, precision sensors, battery charging, and production-ready KiCad deliverables. I can take this design through the four proposed milestones: verified schematic and pin mapping, placement and stack-up review, controlled-impedance routing with clean power/ground architecture, and a complete manufacturing package. Particular attention will be given to the QM35825 UWB paths and antenna clearances, NFC matching network, RF isolation, BGA escape strategy using standard through-via fabrication, and the thermally isolated MAX30205 island. I will also review component availability, footprints, decoupling, power sequencing, and assembly constraints before final release. My background includes full consumer-grade product development from concept through prototype and production, so I can also support board bring-up and firmware integration if needed.
