Automotive OBD-II / CAN / K-Line Hardware Engineer

@Mahmoud00Ibrahim

Hi, I’m an Automotive Electronics / PCB Design Engineer with hands-on experience in vehicle tracking and telematics hardware, including CAN interfaces, automotive power protection, MCU-based systems, and vehicle-grade PCB design. I can extend your existing platform into a common OBD-II hardware architecture supporting: • CAN for modern vehicles • CAN + K-Line for legacy vehicles • Configurable BOMs for both variants • Automotive power input protection, filtering, and transient handling • Robust OBD-II interface design and communication circuitry I can handle the updated schematic, component selection and alternatives, BOM, interface design, protection circuitry, and complete design documentation while keeping the architecture practical for production. I fully understand the proprietary nature of the project and am comfortable executing an NDA before reviewing any confidential design information. I can also provide relevant examples of my previous automotive tracking/telematics and CAN-based hardware work. Ready to start immediately after NDA.

As a seasoned electrical engineer with years of experience in various industrial automation projects, I am confident that I am the right fit for your automotive OBD-II / CAN / K-Line hardware undertaking. You see, I've worked extensively with protocols such as OBD-II, CAN Bus, and K-Line - specifically designing and implementing automotive power supply/protection measures, PCB schematic design, and vehicle telematics hardware. Furthermore, I have a profound grasp on the need to create a common hardware platform when possible, while ensuring distinct BOMs/configuration options for different variants. I will leverage this knowledge and my expertise to create a comprehensive solution that meets your specific requirements. While confidentiality will be adhered to stringently as expected from any professional, my diverse portfolio showcases my versatility and commitment to upholding the stipulations of NDAs. I aim not just to meet your expectations but to exceed them by delivering top-notch results such as updated schematic, BOM, component selection/alternatives, interface design, automotive protection circuitry, and detailed design documentation on time and in line with predetermined specifications. Let's collaborate!

Hi, I have done similar work before where I have developed the device for OBD II port which fetch the acceleration, braking and other data from the port and display it on 3.5 inch screen powered by USB C port. I am comfortable with sharing NDA and I have working experience with ESP32, nRF and STM32 controllers and integrating them with IMU sensor. Thanks Kiran

Hi, I’m very interested in this project because I have **15+ years of R&D experience in automotive electronics, PCB design and vehicle telematics**. I have completed an **AIS-140 GPS Tracker** project and other vehicle-oriented embedded systems involving GNSS, cellular communication, automotive power and real-time data acquisition. I have hands-on experience with **CAN-based automotive interfaces, OBD-II architectures, automotive power protection and embedded hardware design**. I can review and extend your existing tracker design toward a common OBD-II hardware platform supporting **CAN for modern vehicles and CAN + K-Line for older vehicles**, with appropriate BOM/configuration options. For the initial phase, I can handle component selection and alternatives, CAN/K-Line interface circuitry, automotive transient/reverse-polarity/over-voltage protection, power supply design, schematic updates, BOM and complete design documentation. My telematics experience is particularly relevant to this project, including vehicle tracking hardware, GNSS, cellular communication and compact embedded PCB design. I understand the importance of robust automotive interfaces and protection rather than treating the OBD connector as a generic digital interface. I’m comfortable working under NDA and handling proprietary designs confidentially.

Hi, I can modify and extend your existing telematics hardware for the two OBD-II variants, with a common platform and configurable BOM where practical. I can handle: * CAN interface and automotive transceiver design * K-Line interface for legacy vehicles * OBD-II connector/interface design * Automotive power input protection * Updated schematic and PCB design * Component selection and alternatives * BOM and design documentation * Hardware considerations for vehicle electrical environments I understand the proprietary nature of the project and can proceed under NDA before reviewing the existing architecture. **Budget:** ₹12,500 fixed **Timeline:** 7–10 days for the initial hardware design phase I can start immediately after NDA execution and access to the existing design.

Hi, The key challenge here is not simply adding CAN and K-Line interfaces—it is creating a reliable automotive platform that can support both modern and legacy vehicles without unnecessarily duplicating the hardware. I can help you achieve that with a common PCB architecture and BOM/configuration strategy for the two variants. I have experience with automotive electronics, embedded hardware, PCB schematic design, CAN interfaces, automotive power systems, transient protection, and vehicle communication circuits. I can work on the complete hardware modification, including the OBD-II interface, CAN transceiver, K-Line interface, automotive power input, reverse-polarity protection, load-dump/transient protection, filtering, and appropriate component selection. I will also review the existing architecture and identify where the current design can be reused, improved, or made configurable between the modern CAN-only and CAN + K-Line versions. Initial deliverables will include the updated schematic, complete BOM with MPNs and alternatives, interface design, automotive protection circuitry, and clear engineering documentation. I understand that the existing product is proprietary and am comfortable working under NDA. **Send me the NDA and the project requirements—I am ready to go through the existing architecture and determine the cleanest way to turn it into a robust dual-variant OBD-II telematics platform.** Best regards, António
