Automotive Driver Warning System Redesign

@shivkantverma

Hi, Greetings! I am interested in working on your project. Could you please share the design details and technical requirements so we can discuss the project scope and key parameters in detail? I look forward to working with you. Thank you!

Hi, I can develop the **complete automotive DWS schematic in KiCad**, starting from the system requirements and architecture, with PCB layout kept strictly out of scope until your written approval. I have **16 years of embedded hardware/PCB R&D experience**, including **AIS-140 GPS trackers, automotive telematics, GNSS/cellular systems, IMU integration and vehicle electronics**. I have also worked with STM32/ESP32-class MCUs, wireless modules, RS485/CAN-related systems and custom PCBs. For the first milestone, I’ll deliver the **system block diagram, power tree and major component selection**, including alternatives for MCU, GNSS, wireless, IMU, storage and power-management devices. The schematic will address **12/24V automotive input protection**, including reverse polarity, load-dump/transient protection, cold-crank considerations, filtering, fuse/PTC, ESD, grounding and power integrity. I’ll also reserve well-defined interfaces for future **CAN, camera, microphone, ToF/LiDAR and mmWave** expansion without adding those features to the base design. I can provide: * Editable KiCad schematic * Pin map and interface matrix * Preliminary BOM/MPNs * Automotive protection design * GNSS/RF design notes * Test-point plan * ERC-clean project * Design notes and open issues I’m comfortable working under NDA and can base the design on your proprietary requirements once provided.

I can develop the complete KiCad schematic for your DWS from the system requirements and proprietary architecture, with a strong focus on automotive power protection, signal integrity, and production readiness. I would begin with Milestone 1: system block diagram, power tree, major component selection, alternatives, pin/interface planning, and key engineering risks. After written approval, I would complete the ERC-clean schematic, pin map, interface matrix, preliminary BOM, automotive protection, RF/GNSS notes, test-point plan, and design documentation. PCB layout would not begin before your approval. For the 12/24 V automotive input, I would address reverse polarity, fuse/PTC protection, load dump, cold crank, surges/transients, ESD, input filtering, grounding, and low-noise power rails. The architecture would also reserve practical expansion paths for CAN, camera, MEMS microphone, ToF/LiDAR, mmWave, and additional safety sensors without adding unnecessary cost to the first prototype. I have hands-on experience with STM32/ESP32-class embedded systems, GNSS/wireless interfaces, IMUs, power electronics, low-power architectures, and KiCad schematic/PCB development with production-oriented component selection and BOMs. I understand the NDA and proprietary nature of this project and will strictly follow your approval process for major component changes and optional features.
