1OVERVIEW
1.1 GENERAL INFORMATION
The VEST E2I-Plus carrier board was designed to use the Vest E2I-Plus SOM that uses NXP’s i.MX 8M Plus
applications processor. Together they enable a smooth transition from conventional Human Machine
Interface (HMI) to an advanced interactive user interfaces that support multimedia, touch, wireless
connectivity, machine learning and more. Two views of the carrier board are shown below.
