I will design multi layer pcb for the sensor interface

Need a reliable PCB that bridges sensors, microcontrollers, and real-world signals? I design clean, professional 2-layer PCBs for embedded and IoT projects from schematic capture to fully routed, manufacturable boards.

As a portfolio example, I've designed a 10-channel analog interface PCB built around an ESP32, using optocoupler-isolated inputs (4N35), voltage attenuation, and buffered signal paths to safely convert 9V sensor signals down to 3.3V logic levels for stable microcontroller interrupt triggering. This is shown in my gig gallery as proof of the quality and complexity I work at.

What I offer:

Schematic capture

multi-layer PCB layout and routing

Signal conditioning circuits (voltage dividers, buffers, optocouplers, relays)

Microcontroller integration (ESP32, Arduino, STM32, and more)

Component footprint selection & BOM (Bill of Materials) preparation

Design for Manufacturing (DFM) checks

Gerber, drill, and pick-and-place files ready for fabrication

Why work with me:

• Real hands-on experience building functional, tested hardware not just theoretical designs
• Clear communication throughout the process
• Designs that are optimized for manufacturability
