You will get Custom PCB Design for ESP32 & Embedded Systems Projects
Project details
I provide professional PCB design solutions for IoT, embedded systems, and electronics projects. From single-layer prototypes to multi-layer production-ready boards, I deliver fully tested schematics, optimized layouts, and Gerber files ready for manufacturing. My designs focus on signal integrity, reliability, and cost-effective component placement.
Whether you need a basic proof-of-concept PCB or a complete system for industrial or consumer electronics, I combine hands-on electronics experience, ESP32/STM32 expertise, and PCB design best practices to bring your ideas to life efficiently and professionally.
What sets this project apart:
End-to-end PCB design workflow (schematic → layout → production files)
Multi-layer and high-speed routing expertise
Industry-standard tools (KiCad, Altium, EasyEDA)
Optimized for IoT and embedded firmware integration
Support for design revisions and manufacturing consultation

If you need embedded firmware that is stable, connected, scalable, and maintainable—let’s talk.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT I BUILD FOR CLIENTS
✅ IoT Firmware Development
End-to-end IoT firmware on ESP32, STM32, and ATSAM microcontrollers. MQTT over TLS, secure boot, OTA firmware updates, and low-power wireless design for battery-operated devices. I write firmware that runs in production — not just demos.
✅ Industrial Automation & Modbus Integration
Modbus RTU and Modbus TCP firmware for industrial sensors, VFDs, PLCs, and energy meters over RS-485. FreeRTOS multitasking with concurrent Modbus polling, PID control loops, and cloud data publishing. Built for 24/7 uptime.
✅ Cloud-Connected Embedded Systems
Full IoT pipeline: device firmware → MQTT broker → AWS IoT Core / Azure IoT Hub → time-series database → Grafana or custom dashboard. Experience with EMQX, Mosquitto, Firebase, and Docker-based deployments on Raspberry Pi.
✅ BLE & Wi-Fi Device Development
Bluetooth Low Energy (BLE) firmware for sensor devices, wearables, and gateways. BLE GATT profiles, custom services, DFU (Device Firmware Update) over BLE. Wi-Fi provisioning, WPA2 enterprise, and mesh networking on ESP32.
✅ Flutter Mobile Apps for IoT
Cross-platform iOS and Android apps that connect to your hardware via BLE, MQTT, or REST API. Real-time sensor dashboards, device configuration screens, push alerts, and OTA trigger from mobile. Flutter + Firebase or Flutter + custom backend.
✅ PCB Design for Embedded Systems
Schematic capture and PCB layout in KiCad, EasyEDA, and Altium Designer. ESP32 and STM32 custom boards, power supply design, EMC considerations, and Gerber files ready for manufacture. DFM-reviewed layouts for production.
