The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
A system basis chip (SBC) is an integrated circuit that includes various functions of automotive electronic control units (ECU) on a single die. [1] [2] It typically includes a mixture between digital standard functionality like communication bus interfaces and analog or power functionality, denoted as smart power.
An ECU from a Geo Storm. An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.

123D Circuits In-browser circuit design and PCB layout tools. Created by Autodesk, it is free to use, zero-install and web based. There's a limited library of components to use. There are 3 drawing modes: schematics, PCB and breadboard diagram. The PCB editor does not do automatic routing.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
A schematic editor is a tool for schematic capture of electrical circuits or electronic circuits.. Schematic editors replaced manual drawing of schematic diagrams, but they still retain the capability of outputting schematics on specially formatted sheets.
