(RGB LCD, SC LVDS and HDMI). This version is the standard config-
uration of the carrier, which is fully compliant with SMARC specifica-
tion 1.1. This standard version supports one RGB LCD display, one
single channel LVDS (18/24 bit) display, and one HDMI display.
LEC-BASE MINI Custom

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 MINI 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 MINI 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 MINI.
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
Height (overall) 33 mm
Board thickness 2 mm
Width 170 mm
Length 237 mm

2.2 Standard Hardware References
This section further describes the supported features of the LEC-BASE MINI standard, on-board
hardware.
2.2.1 Audio IO Jacks
The LEC-BASE MINI provides two standard audio jacks for HD (CN21) and I2S (CN56) audio.
Two audio codecs support these two interfaces. Figure 2-4 depicts the three lines of the audio
jacks: Line In (1 - Blue), Line Out (2 - Green), and MIC In (3 - Pink). Figure 2-5 presents the
functional block diagram of I2S signals and hardware on the carrier.
