4.3 The SPI/TE/Reset/backlight pin-header (J102)
This connector connects to the display’s SPI interface and backlight to the AVR
XMEGA’s digital PORTD that is available on the “AVR XMEGA PORT D” pin header
on the Xplain board(J102). Please see Table 4-3 page below for pin-out description.

4.4 The unused pin-header (J105)
This connector is not used for electrical connection on the Display Xplained module. It
is only used as mechanical stabilizing to the Xplain kit.
4.5 The LCD connector (J100)
The LCD connector is a 40-pin FPC connector with 0.5mm pitch. For details on
signal/power connections, see the schematic diagram for the Display Xplained
module.
5 Available code examples and drivers
A Getting-Started training for the Display Xplained kit can be downloaded from the
Atmel web site. The application note is called: AVR1913: Display Xplained
Firmware – Getting Started training.
Further information and drivers for Display Xplained can be downloaded as
application notes, also distributed from Atmel’s web site.
6 Mounting Display Xplained module to Xplain kit
The Display Xplained module will fit onto the expansion connectors on the Xplain kit.
Be careful to rotate the Display Xplained module correctly to the Xplain kit. The text
direction should be the same on both when rotated correctly. Also be careful to align
the connectors to avoid wrong signal/power connections that might cause damage to
the boards.
Also be careful when the Display Xplained module is removed to avoid bending pins.
Don’t use any hard tools that might cause damage to the boards. Pay attention to
EMC guidelines and proper handling precautions to avoid ESD damage to the
boards.
