Currently working on the hardware design for a custom ECU based on the [Insert MCU, e.g., STM32/Infineon]. I’m in the pinout assignment phase, and honestly, it’s one of those tasks that looks easy until you actually start dragging nets across the schematic.

While designs vary by manufacturer, most pinouts include the following standard categories: www.soulinconn.com How to Read ECU Pinout Diagrams, Wiring & Connectors

ECU pinout is a specialized reference map that identifies the specific function of every terminal (pin) on an Electronic Control Unit's connector. In ECU design and troubleshooting, this diagram is the "master key" for connecting power, grounds, sensors, and actuators to the vehicle's brain. www.soulinconn.com Core Components of ECU Pinouts
