Custom PCB Embedded Hardware Engineer Altium, KiCad EasyEDA
Hey! I’m a PCB layout & hardware design engineer expert in high speed, compact, and production ready circuit board designs. Whether you need a CAN Bus module, an automotive LED driver, or custom contr...
About this Gig
Need to read vehicle telemetry, interface custom sensors with your standalone ECU, or build an OBD-II logging device? I design compact, noise immune CAN Bus and OBD2 interface PCBs for automotive and industrial applications.
I'm an expert in integrating microcontrollers (ESP32, STM32, RP2040) with dedicated CAN transceivers (MCP2515, TJA1050, SN65HVD230) to give you reliable vehicle communication.
What you will get;
Low noise differential trace routing for CAN-H and CAN-L
OBD-II male/female connector PCB mounting setups
Complete Gerber & Drill manufacturing package
Centroid/CPL & LCSC BOM files for JLCPCB assembly
Integrated 12V-to-5V/3.3V step down power regulation
TVS diode protection against load dump spikes
Native source files (KiCad, EasyEDA, or Altium)
I pay strict attention to ground planes, impedance matching, and split power planes to ensure your CAN node operates reliably without packet drops or signal reflections.
Message me with your pinouts, enclosure limits, or component preferences today to get started!
FAQ
Can you design a board that interfaces with standard aftermarket ECUs like MaxECU or Speeduino?
Yes! Whether you are building an expansion node, a custom display controller, or a sensor translator, I design CAN hardware using standard baud rates (250k, 500k, 1M) matching your ECU specs.
Does the board support both 12V automotive and 24V commercial vehicle systems?
Yes. Let me know your operating voltage requirement upfront, and I will select automotive power regulators rated up to 36V/40V input to handle both passenger car and heavy-duty truck electrical systems.
What transceivers do you use for CAN communication?
I commonly use popular, easily sourced ICs like the MCP2515 (with MCP2551/TJA1050 transceivers), SN65HVD230 for 3.3V systems, or integrated chips like the ESP32-S3 using internal CAN controllers (TWAI).
Do you include impedance matching for the CAN differential traces?
Yes. I route the CAN-H and CAN-L signals as a 120-ohm differential pair with matched trace lengths, and place onboard 120-ohm termination resistors with jumper options if needed.
Will I be able to edit the project later if I need to change a component?
Yes! I provide complete native source files (KiCad .kicad_pro, EasyEDA .json, or Altium .PcbDoc depending on your chosen package) so you or another engineer can modify the board anytime.
