I will design automotive can bus obd2 j1939 ecu pcb

Building a device that has to talk to a vehicle? I design PCBs that connect your electronics to CAN, CAN FD, OBD2 and J1939 networks and survive a car's harsh electrical environment.

What I design:

OBD2 / OBD-II dongles and diagnostic interfaces

CAN and CAN FD interface boards, loggers and gateways

J1939 boards for trucks, buses and off-highway machines

ECU-style controller boards with MCU, CAN, LIN and I/O

Vehicle sensor, relay and actuator control boards

Every board is laid out for automotive conditions: 936V input, reverse-polarity and load-dump protection, TVS/ESD on the bus lines, correct CAN termination and clean grounding.

You receive:

Schematic and PCB layout (KiCad, Altium or EasyEDA)

Gerber, drill, BOM and pick-and-place files

3D render and STEP model

Source files you fully own

Send me your requirements, a block diagram or an existing schematic. Please message me before ordering so I can confirm layer count, scope and timeline.

Firmware is not included but can be quoted separately.
