The automotive industry is in the middle of its largest transition in its history as OEMs begin to switch from gasoline- and diesel-powered vehicles to electrified versions.

Most OEMs are eyeing a transition that will happen over the next decade with a majority of vendors saying by 2035, fleets will be electrified. Some are starting faster than others and rolling out new vehicles that can take advantage of consumer demand for new electric vehicles (EVs).

Ford has gotten involved big time with its own plans for multiple EVs coming. It also released its Ford F-150 Lightning, an electrified version of its most popular pickup.

The F-150 Lightning electronic control unit (ECU) is the heart of the vehicle that controls the major components of the vehicle including applications processors for advanced driver assistance systems (ADAS) and more.

The following is a partial deep dive into the F1-50 Lightning ECU.
