I will design automotive can bus obd2 j1939 ecu hardware pcb
About this Gig
Need a rugged, noise-immune electronic module for a vehicle application? I specialize in designing robust, production-ready hardware architectures built to survive harsh automotive environments. From simple diagnostic breakouts to complex multi-layer ECU gateways, I turn your concept into a reality.
What I Design:
- Vehicle Networks: CAN bus, CAN FD, LIN, and J1939 architectures.
- Diagnostics & Loggers: OBD2 interfaces, data loggers, and J2534 hardware.
- ECUs & Telematics: Microcontroller circuits with BLE, Wi-Fi, and LTE links.
Automotive-Grade Protection Features:
Every circuit includes strict safety measures: ISO 7637-2 transient voltage protection (TVS), reverse polarity defense, optimized thermal management, and differential pair routing for absolute EMI/RFI noise immunity.
Deliverables Included:
- Production-ready Gerber & NC Drill manufacturing files.
- Component-matched BOM with direct Mouser/DigiKey sourcing links.
- Precise 3D STEP models for mechanical enclosure fitting.
- Native source files (Altium, KiCad, or OrCAD).
Before placing order kindly contact me!

FAQ
What information do I need to provide to start the project?
Please provide your schematic circuit requirements, your desired microcontroller platform (e.g., STM32, ESP32, NXP), the exact automotive interfaces needed (CAN, OBD2, J1939), and any physical size or enclosure constraints for the board.
How do you protect the PCB against vehicle electrical noise and voltage spikes?
Every design follows strict automotive engineering standards. I implement TVS diodes for ISO 7637-2 load dump protection, reverse polarity protection, isolated ground planes, and specialized differential pair routing to guarantee EMI/RFI noise immunity on CAN lines.
Which PCB design software do you use to deliver source files?
I primarily design using Altium Designer, KiCad, and Cadence OrCAD. Please specify your preferred software when placing your order so I can provide the native source files accordingly.
Are the manufacturing files you deliver ready for instant production?
Yes. You will receive production-ready Gerber files (RS-274X), NC Drill files, assembly drawings, and a fully structured Bill of Materials (BOM) with verified manufacturer part numbers (MPNs) from Mouser or DigiKey.
Do you write the firmware or code for the ECU / CAN bus controller?
This Gig strictly covers hardware schematic design and PCB layout. However, if you require embedded firmware development for your microcontroller, please contact me before ordering so we can discuss a custom scope of work.
