I’m Avi Gupta, an electronics and PCB design specialist with 11+ years of experience and 500+ boards shipped for IoT, industrial, medical, and consumer products. I turn your idea or rough prototype into production-ready hardware using Altium Designer and other industry tools. ✅ What you really get working with me • Designs aimed to pass EMI/EMC and safety – not just “it seems fine” • Architecture and layout that reduce respins, delays, and surprise costs • Clean, production-ready documentation your manufacturer can build from ✅ I’m a good fit if you: • Have an ESP32/STM32 (or similar) prototype and need a robust Altium design for production • Already have a board but are worried about noise, reliability, thermal issues, or compliance • Want a senior hardware mind owning electronics while your team focuses on firmware/apps ✅ How I can help 1. New product hardware design • System architecture and block diagrams (MCU, power, IO, connectivity) • Schematics in Altium (KiCad/Eagle possible on request) • Multilayer PCB layout with controlled impedance, length matching, solid grounding • DFM-focused layout so CMs can assemble and test smoothly 2. PCB review, cost-down & reliability upgrade • Schematic/layout review for SI/PI, EMI/EMC, grounding, protections • BOM and PCB cost reduction (alt parts, stack-up, routing optimizations) • Better thermal behavior and reliability for 24/7 environments • Moving you from “lab-only prototype” to “production-grade design” 3. Compliance-conscious, production-focused design • Design practices aligned with CE, UL, CISPR and EMI/EMC expectations • Grounding, filtering, shielding, creepage/clearance planning • Full outputs: schematics, PCB files, Gerbers, fab/assembly files, BOMs, PDFs ✅ Sample project types • ESP32-based LoRa/RS485 industrial IoT nodes • STM32 industrial controllers with isolated IO, 24 V domains, RS485/CAN • Raspberry Pi HATs with sensors, relays, RGB indicators and field wiring • High-voltage / high-power PCBs with isolated gate drivers and current sensing • Cost-optimized redesigns of existing ESP32/STM32 boards ✅ Tools & technologies Altium Designer (primary), plus KiCad, Eagle, EasyEDA, Proteus MCUs: ESP32/ESP8266, STM32, NXP, TI Interfaces: RS485, Modbus, CAN, Ethernet, SPI, I²C, UART, USB Wireless: Wi-Fi, BLE, LoRa (modules) Applications: IoT, industrial control, sensing, data logging, power and battery-powered products ✅ How I work • Hardware-first: solid architecture and PCB design, with basic firmware bring-up support • Clear communication: upfront questions, regular check-ins, review milestones • Production mindset: I design as if your board will be built at scale, even for 5–10 units If you need a reliable hardware partner for a real product (not a hobby build), message me with your idea, current status, and target timeline. Let’s make your hardware ready for the field. less -
