The HDK670 display card is an additional PCBA that mates with the display connector
J1301 on the carrier board. This board allows users to interface with the development kit
via the LCD that comes preinstalled on the display card. Table 3.9-2 illustrates the
interfacing connectors on the display card.

3.9.2.1 Connecting the Display Card to the Development Kit

This configuration allows the user to use the preinstalled LCD display that comes with the
display board. As shown in the block diagram below, the MIPI DSI0 lines, which come from
the 100-pin ERM8 connector, directly connects to the TFT panel. See the section below for
more details on this LCD panel. It is important to note that connector J0501 of the display
card needs to connect to J1301 of the carrier board for this configuration to work.
