Hi, I’ve read your requirements carefully and can review the complete schematic before PCB layout, checking all nets, connections, footprints, floating pins, and potential design issues. I’ll also review the high-speed signals, power rails, current requirements, and decoupling, then provide an annotated schematic and a concise report with the findings and recommended changes. I work with **Altium Designer and KiCad**. Please check my portfolio for my previous PCB design work. I’m ready to start once you share the schematic. Best regards, Ahmed

Hi, I can review your double-layer PCB schematic thoroughly before layout and identify electrical, connectivity, footprint, power, and signal-integrity issues. I can check: • Every component pin and net connection • Floating/unconnected pins and duplicated nets • MCU/IC power, reset, clock, programming, and interface circuits • Sensor and actuator interface correctness • Footprint/pin-number consistency • Pull-ups, pull-downs, protection, and filtering • Decoupling capacitor values and placement requirements • Power-rail current capability and regulator loading • Grounding and return-path considerations • Higher-speed digital interfaces for signal-integrity risks • Connector pinouts and polarity • ERC warnings and design-rule concerns I can work with KiCad or Altium files and perform the review entirely in the EDA environment. Deliverables: • Annotated schematic/PDF with clearly marked findings • Prioritized list of critical, major, and minor issues • Signal-integrity and power-distribution review notes • Recommended schematic/design corrections before PCB layout I’ll highlight any critical issue immediately rather than waiting for the final report. Best regards Ankit

Hi, I'm an Electronics and Communications engineer graduated from Cairo University with 5+ years of hands-on experience in analog-digital electronics, ICs, sensors, actuation nodes and PCB design. With sharp eyes and attention to small details, I'll check the wiring of every single net confirming no floating pins, duplicated nets, or mismatched footprints, and make sure the power is distributed well across the circuit to eliminate the risk of resetting the MCUs and power fluctuations. I'll also check the signal integrity of every IC and component on the circuit. I'll also give you my suggestions if needed based on my practical experience, I can help with the code too. I'll deliver: 1. An annotated version of the schematic (PDF or native file) showing all corrections and comments. 2. A concise report summarizing signal-integrity results, power analysis findings, and any recommended design tweaks Send me the design and let's get started!

@antoniod83

Hi, I can review your schematic thoroughly before layout, focusing on both electrical correctness and production-level design considerations. I’ll check every net and component for floating or incorrectly connected pins, duplicated/mismatched nets, footprint compatibility, power connections, and interface consistency. I can also review the higher-speed MCU/IC interfaces for signal-integrity risks and evaluate the power distribution, current requirements, decoupling, grounding, and potential voltage-drop issues. I’m experienced with KiCad and PCB design, including power supply design, EMC considerations, signal integrity, and hardware reliability. I can work from your native KiCad/Altium files or exported formats. Deliverables: * Annotated schematic with corrections and technical comments * Concise report covering SI, power distribution, and recommended improvements * Immediate highlighting of any critical issues that could affect functionality or PCB layout Please send the schematic/BOM and relevant datasheets, and I can start with a detailed net-by-net review.

@daliagrimal

Hi, I can review your design directly in Altium Designer, with a systematic, component-by-component check rather than just a quick schematic inspection. I’ll focus on catching issues before they reach PCB layout: incorrect or missing connections, footprint mismatches, power integrity, decoupling, and high-speed signal risks. Any critical issue will be flagged immediately so you can act on it. You’ll receive a clearly annotated schematic plus a concise, actionable report—not just a list of errors, but specific recommendations for improving the design. If needed, I can also review the PCB layout afterward. Best regards.

@JagdishCK

I understand that your project involves a double-layer PCB combining microcontrollers, ICs, passive components, and sensors and you want a thorough schematic review before moving to PCB layout. I can review the complete schematic connection-by-connection to identify floating pins, incorrect or duplicated nets, footprint mismatches, and other electrical issues. I can also review high-speed signals for potential signal-integrity problems and check the power rails, current requirements, grounding, and decoupling. With my practical experience in PCB and embedded hardware design, I can provide clear annotations, recommendations, and a concise report, while immediately highlighting any critical issues that need attention.
