About this Gig
Hello and Welcome!
Modern OBD-II diagnostic devices require much more than reading vehicle fault codes. A reliable automotive solution must accurately interface with ECU communication protocols such as CAN, CAN FD, ISO 9141, K-Line, J1850, and UDS while ensuring signal integrity, EMC compliance, low-power operation, and real-time embedded processing. From hardware architecture to firmware optimization, every subsystem must be engineered for dependable performance in demanding automotive environments.
I specialize in developing custom OBD-II diagnostic devices, automotive PCB designs, and embedded firmware for vehicle diagnostics, telematics, fleet management, data logging, and IoT applications.
What I Will Provide:
- Custom OBD-II Hardware Architecture
- Embedded Firmware Development (ESP32, STM32, NXP, Nordic)
- CAN Bus, CAN FD, ISO 9141, K-Line & J1850 Integration
- ECU Communication & Diagnostic Protocol Implementation
Why Choose Me?
- Specialized in Automotive Embedded Systems & PCB Design
- Experience with OBD-II, CAN Bus, and ECU Communication
- Optimized PCB Layout for Signal Integrity & EMC Performance
