3.1.2 Functionality and interfaces
Core of the system is the soldered processor module TQMLS1012AL with an ARM Cortex A53 based NXP Layerscape series CPU
LS1012A. In addition to the standard communication interfaces such as USB, Ethernet, etc., more TQMLS1012AL signals are
routed to a 100 mil pin header on the MBLS1012AL.
The MBLS1012AL provides the following interfaces and functions:
