Yousef E.

I provide PCB design, schematic capture, PCB layout, hardware bring-up, and bring-up firmware services using KiCad for ESP32, STM32, automotive electronics, LED lighting, IoT, embedded hardware, and compact electronics products. My focus is reliable layouts, stable power delivery, thermal management, protection, and DFM-aware designs ready for prototyping and manufacturing (Gerbers, BOM, Pick-and-Place / CPL), including JLCPCB, PCBWay, and other PCB fabrication / assembly workflows. What I help clients avoid: • Noisy ADC readings caused by poor grounding or PCB layout • Unstable regulators, weak power rails, or power supply issues • USB, UART, CAN, RS-485, SPI, or I2C communication problems from routing mistakes • Automotive power-input issues including transients and reverse polarity • Relay, MOSFET, current-sensing, and voltage-sensing circuit problems • LED thermal and power distribution problems that reduce performance or lifespan • Costly PCB re-spins caused by avoidable design errors Recent work includes: • ESP32 boards with USB-UART, native USB, auto-programming, Wi-Fi, and BLE • STM32 mixed-signal boards with analog / digital grounding and layout separation • Automotive 12 V electronics with protected inputs, relays, MOSFET drivers, current sensing, voltage monitoring, and CAN • Buck and buck-boost converters, battery charging circuits, filtering, and stable power stages • LED arrays, LED strips, and custom lighting PCBs • Compact PCB designs for wearables, consumer products, and small-form-factor electronics • Hardware bring-up and test firmware for verifying power, USB, wireless connectivity, sensors, ADCs, I2C devices, and charging circuits • Oscilloscope-based debugging and signal verification • Microcontroller development boards for embedded systems prototyping What I deliver: • Circuit design, schematic capture, and PCB layout • LED lighting, automotive, and embedded hardware PCB design • Compact and space-constrained PCB layouts • Grounding, decoupling, protection, and power distribution strategy • USB differential pair routing and interface design • 2-layer and 4-layer PCB stackups • Hardware bring-up, test firmware, and troubleshooting • Gerbers, BOM, Pick-and-Place / CPL files • Manufacturer-ready outputs for JLCPCB, PCBWay, and other PCB fabs I aim to deliver practical, production-ready hardware designs that reduce iteration time and help projects move smoothly into prototyping and assembly.
