I have worked on embedded systems involving real-time data processing, sensor integration, and UI display logic, so I am comfortable handling both hardware + firmware + system design together. My Approach: I will design a microcontroller-based system that reads all inputs (speed, voltage, indicators, etc.), processes them in real time, and drives a smooth TFT display with no lag. The focus will be on stability, accuracy, and EMI-safe design for automotive use. Recommended Setup: MCU: STM32 series (reliable, fast, strong peripheral support for CAN/UART, widely used in automotive) Display: 3.5”–4.3” IPS TFT (good sunlight visibility, better viewing angles) Communication: CAN + UART support, with fallback for pulse-based speed input Deliverables:- • Complete schematic + PCB (KiCad/EasyEDA) • Gerber + BOM (production-ready) • Firmware (speed calc, odometer storage, fault logic, UI handling) • Clean UI (speed, battery, indicators, warnings) • Support for prototype testing Experience: I Have ve worked on real-time systems (including vision + embedded integrations), so handling timing, filtering noisy signals, and stable data display is something I take seriously. Timeline: 2 weeks (design → PCB → firmware → testing support) If you have enclosure constraints or reference designs, I can align the PCB accordingly. Let’s discuss details and finalize specs.

Hi, I’ve reviewed your requirements, and this aligns well with my experience in embedded systems and automotive-grade PCB design. I’ve worked on ESP32/STM32-based systems with displays, sensor inputs, and real-time data processing, including EV-related applications. For your digital cluster, I recommend using an STM32 MCU for reliable real-time performance, paired with an IPS TFT display (3.5”–4.3”) for good sunlight visibility and smooth UI. Communication can be handled via UART/CAN, with proper filtering for noisy automotive signals. My approach: • Accurate speed & distance calculation (pulse or CAN-based) • Stable power design (12V → 5V → 3.3V with protection & filtering) • EMI-resistant PCB layout with automotive connectors • Smooth UI with fast refresh and optional startup animation • Reliable storage (EEPROM/Flash) for odometer data Deliverables include full schematic, PCB, Gerbers, BOM, firmware, and UI design with bring-up support. I’ve built similar display + control systems and can share examples/screens once we connect. Estimated timeline: 10 days with milestone-based progress. Best regards, [Ahmed Yahia]

Hello, I can help you design a reliable, automotive-grade digital instrument cluster tailored for electric 2-wheelers and 3-wheelers. I specialize in embedded systems and precision instrumentation, with experience developing robust, real-time electronics for harsh environments. I will deliver a complete end-to-end solution including schematic, compact PCB, firmware, and UI—optimized for smooth performance, sunlight visibility, and EMI resilience. For this project, I recommend an *IPS TFT display (3.5”–4.3”)* for better outdoor readability and wide viewing angles, paired with a high-performance MCU, ensuring fast UI rendering, accurate signal processing, and reliable CAN/UART communication. The system will support all required inputs (speed, voltage, indicators, brake, etc.), with precise speed/distance computation, non-volatile odometer storage, and fault handling. The PCB will be designed with automotive-grade practices—robust power conditioning, filtering, and vibration-resistant layout. What you’ll get: * Complete hardware design (schematic + PCB + Gerbers) * Optimized BOM with exact components * Firmware (modular, scalable, fast-refresh UI) * Clean and intuitive UI design (with startup animation if needed) * Debugging and prototype support **Timeline:** ~6–12 weeks (including design, firmware, and initial testing) You can find relevant automotive work samples within my portfolio.
