Engineering reference library · Vehicle and EV electronics
Automotive Electronics PCBA Examples
Twenty reference architectures expose the power, communications, sensing, embedded-control, validation, and production-release decisions behind vehicle and EV electronics—not just board photos.
Control coremmWave transceiver, antenna array, signal processing, and diagnostics
Critical inputsRadar returns, vehicle state, mounting geometry, and calibration data
Validation focusFrequency and performance confirmation, OTA scenarios, EMC, weather, and mounting tolerance
ArchitectureVehicle input, communications, sensing, control, and power stages.
Risk focusTransient, thermal, RF, functional safety, lifecycle, and integration.
VerificationBench, fault, environmental, EMC, vehicle, and production test planning.
EvidenceStandards are validation targets only when defined in project scope.
Explore the reference architectures
Filter by subsystem or search by function. Open any example for architecture, engineering challenges, validation planning, and the development work needed to move from a board reference to a controlled vehicle electronics program.
How to read these examples
They are technical references, not off-the-shelf products, certification claims, or proof of a customer relationship.
Automotive architecture matrix
What changes across vehicle and EV electronics
Power source, load type, vehicle interfaces, sensing role, safety boundaries, environment, and lifecycle expectations determine the architecture and verification plan.
Swipe horizontally to compare control and load, inputs and interfaces, and validation focus.
| Application group | Control / load | Inputs / interfaces | Validation focus |
|---|---|---|---|
| Connected & Vision | Diagnostics, video, telematics, or phone-projection processing | Protected power, OBD or CAN, USB, camera and storage, GNSS, cellular, Wi-Fi, or Bluetooth as applicable | Transient recovery, compatibility, RF or video behavior, thermal limits, and secure data or update handling |
| Power & Portable | Power conversion, motor control, charging, or coordinated high-current loads | Battery or AC source by reference, voltage, current, temperature, pressure, USB power, display, and keys | Source suitability, isolation where applicable, efficiency, load faults, output behavior, and thermal margin |
| ADAS & Safety | Ultrasonic, radar, RF-sensor, or camera processing with driver-warning outputs | Sensor returns, calibration and mounting data, vehicle state, CAN or LIN, RF links, buzzer, display, or video | Scenario coverage, calibration, false-positive and false-negative behavior, RF or EMC, environmental exposure, and fault response |
| Body & Cabin | Motor, relay, lighting, fan, sensing, or resonant wireless-power control | CAN or LIN, position and current sensing, air-quality and temperature inputs, user controls, and external loads | Sleep and wake behavior, stall or obstruction response, thermal performance, EMC, and full-assembly behavior |
| EV & Energy | EVSE protective control or BMS controller development and prototyping | CP or PP, current, voltage, leakage and temperature sensing, CAN, isolated links, or HIL interfaces as scoped | Isolation, protective functions, single-fault behavior, high-voltage system boundaries, and target-market requirements |
From a reference board to a vehicle-ready program
A reference can accelerate architecture decisions, but target vehicle, electrical environment, regulatory market, safety goals, lifecycle, and evidence requirements must be defined for the actual product.
Engineer the platform
Lock protection, network, sensing, diagnostics, thermal, cybersecurity, and fault-handling architecture.
Validate with evidence
Plan bench, HIL, fault injection, EMC, environmental, RF, vehicle, and endurance verification as applicable.
Release and control

What the library demonstrates
Subsystem understanding, architecture decomposition, risk identification, validation planning, and the engineering handoff needed for a custom automotive or EV electronics program.
What it does not claim
Reference images and visible brands are used for technical analysis. They do not imply endorsement, affiliation, an existing customer project, verified automotive qualification, certification, or measured performance. Trademarks belong to their respective owners.
