I provide end-to-end support across architecture, circuit and PCB design, prototype validation, firmware coordination, enclosure integration, manufacturing preparation, and production support. Attention to detail covers power, interfaces, components, grounding, thermal behaviour, RF performance, testability, compliance, sourcing, assembly, and manufacturing. Core capabilities: ✅ Architecture & Feasibility — platforms, power, interfaces, sensing, protection, enclosure constraints, and technical risk. ✅ Advanced PCB Design — up to 32 layers, controlled impedance, differential pairs, length matching, blind/buried vias, HDI, compact layouts, high-current/high-voltage sections, signal/power integrity, grounding, thermal planning, antenna placement, RF keepouts, DFM, DFA, and DFT. ✅ Platforms — Arduino, STM32, ESP32, nRF52/nRF53, NXP, TI, i.MX, Raspberry Pi, and embedded systems. ✅ Tools — Altium Designer, KiCad, EasyEDA, EAGLE, and Proteus, including schematic symbols, PCB footprints, and 3D library data. ✅ Design Review — circuit correctness, protection, lifecycle risk, placement, routing, thermal performance, EMI/EMC, testability, and production readiness. ✅ Prototype Bring-Up — equipped electronics lab for measurement, debugging, validation, fault investigation, and revision support. Relevant hardware areas: 🏭 Industrial automation and monitoring 🏠 IoT and connected products ⌚ Wearable and compact electronics ⚕️ Medical and measurement electronics 🚗 Automotive and transportation hardware 📡 RF, BLE, Wi-Fi, LoRa, and GNSS systems ⚡ Power management, battery systems, and high-current hardware 🛰️ Reverse engineering, design recovery, and benchmarking I work directly with clients and remain involved in architecture, critical decisions, reviews, and communication. PCB Must Innovations supports documentation, prototyping, sourcing, and manufacturing preparation. No unexplained handoffs. No disappearing after the first prototype. I support global clients with overlap across time zones. I am best suited to commercially serious projects where reliability, performance, and production readiness matter more than the lowest quotation. Share your product objective, development stage, files, main concern, quantities, enclosure constraints, and compliance requirements—or book a call. less
