Common Ground Point 2 pin | ESD protection (112) Vero Boards Facility to interface microcontroller devicesCommon Ground Point 2 pin In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the earth. Electrical circuits may be connected to ground (earth) for several reasons.
