1.5 Specifications
1.5.1 Physical
Table 1-2 lists the physical dimensions of the carrier.
1.5.2 Electrical
Table 1-3 specifies the voltage inputs of the carrier.
1.5.3 Environmental
Most components on the LEC-BASE 2.0 carrier are selected as extended temperature range
parts (-40°C to +85°C). Some components are not available in this temperature range. In these
cases, the component temperature ranges are narrower. The LEC-BASE 2.0 is validated in the
-40°C to +85°C range.
The overall system performance depends on the combination of module and carrier subsys-
tems. Some SMARC modules are available in the industrial temperature range. Others are com-
mercial temperature range parts. Similar considerations apply to any of the add-on cards or
peripherals that are used with the LEC-BASE 2.0.
Table 1-4 defines the environmental conditions under which the carrier is qualified to operate
and to be stored.
Table 1-2: Weight and Footprint Dimensions
Item Dimension Overall height is measured from the upper board
surface to the top of the highest permanent
component on the upper board surface. This
measurement does not include the cooling solution,
which can vary. The cooling solution will probably
increase this dimension.
Weight 0.42 kg (0.93 lb)
Height (overall) 37.70 mm (1.48 inches)
Board thickness 2.00 mm (0.08 inches)
Width 170.00 mm (6.69 inches)

This chapter describes the physical specifications of the interface connectors, headers, LEDs,
and switches on the LEC-BASE 2.0. The second section of this chapter, titled Standard Hard-
ware References, further describes the industry standard IO hardware on the carrier.
2.1 Interface Headers, Jumper Headers, Switches, LEDs, and Connectors
This section describes and illustrates the connectors, switches, and LEDs on the
LEC-BASE 2.0. Table 2-1 lists and specifies these components, providing the PCB designator,
signal name, and description of each component. Figure 2-1, Figure 2-2 (PCB designator key),
Figure 2-3, and Figure 2-4 appear after Table 2-1 and illustrate the locations of these user inter-
face components.
