Overview
Arduino shields are meant to extend the capabilities of the Arduino, while also making initial development of a
new device much easier for the user. In this case, our NHD-FT81x-SHIELD provides seamless connectivity and
direct software compatibility for the user when using any of our EVE2 TFT Modules with an Arduino. In
addition, the NHD-FT81x-SHIELD offers the following features:
Logic level shifters to allow the 5V Arduino
to communicate with the 3.3V FT81x
Regulators to allow the Arduino to output
more current to the EVE2 TFT Module
Audio filter/amplifier circuit to utilize the
EVE2 TFT Module’s audio output signal
MicroSD card slot, which allows
expandable storage for data such as
images, video, and audio, etc.

Configuration Options
(1) Power Supply Selection
Since you'll probably be connecting other things to the Arduino (LEDs, sensors, servos) we recommend using a DC power
supply that can provide at least 1000mA of output current.
IMPORTANT NOTE:When using the Arduino + NHD-FT81x-SHIELD connected to an EVE2 TFT Module, a DC power
supply should always be connected to the Arduino’s DC input. This is due to the current limitations of the USB input on the
Arduino.
(2) Arduino I/O Configuration (SPI)
On the NHD-FT81x-SHIELD, six solder jumpers (SJ1, SJ2, SJ3, SJ4, SJ5, and SJ6) have been added to provide flexibility to the
Users’ Arduino selection.
Solder Jumpers SJ1, SJ2, and SJ3 enable the SPI lines on the ICSP header. The MISO, MOSI, and SCK lines are available in a
consistent physical location on the ICSP header (Solder connections fitted by default).
Solder Jumpers SJ4, SJ5, and SJ6 enable the SPI lines on the Arduino Uno’s Digital header. A number of clones do not
include the ICSP header, and therefore this configuration is required to be compatible.

Rev 1.0
[ 6 ]www.newhavendisplay.com
(3) Reset Button
S1 is a reset button for the Arduino, not for the display. This allows access to the Arduino’s reset button which is covered
up when a shield in placed on top of the Arduino for a number of the Arduino models.
(4) Micro-SD Slot
The micro-SD socket CN1 on the NHD-FT81x-SHIELD enables the Arduino to access files for use with the FT81x Graphics
Controller, along with being a storage media for general storage used by the Arduino. The Arduino communicates to both
the Display and micro-SD card over SPI, and some of the communication from the display may request the Arduino for
information which is stored on a file on the card. The Arduino will then access the information on the micro-SD card and
send the information to the Display. The micro-SD card chip select signal is available on the Arduino’s Digital pin 5, while
the card detection signal is available on the Arduino’s Digital pin 3.
(5) Audio Connector
The audio connector JP6 is used for connecting an external 8 Ohm 1 Watt speaker.
SP+ Audio speaker +ve from the onboard amplifier.
SP-Audio speaker -ve from the onboard amplifier.
(6) Audio Amplifier Power Select
This jumper provides the option to select the power supply voltage for the onboard power amplifier.
SJ9 (5V) Audio Amplifier Power Select 5 Volts.(Solder connection fitted by default).
SJ10 (3.3V) Audio Amplifier Power Select 3.3 Volts.
(7) Audio Amplifier Mute/Enable Select
This jumper provides the option to Enable or Mute the onboard amplifier.
SJ7 (Enable) Audio Amplifier Enable (Solder connection fitted by default).
SJ8 (Mute) Audio Amplifier Mute.
The onboard amplifier circuit can also be muted by the AUDIO_SHDN# signal connected to GPIO2 on the TFT-LCD
Controller board.

Arduino Installation Instruction for EVE2 TFT Modules
Before you jump to installing the Arduino project files, make sure you’ve got the correct Arduino IDE
version installed.
Tested Platform Version: Arduino 1.8.1
FTDI/Bridgetek has Arduino example code ready to go for use with the NHD -FT81x-SHIELD. You will
need to download the project files and unzip the package onto a respective project folder and open the
solution/sketch file in the project folder and execute it.
Visit Newhaven Display’s GitHub page and download the Arduino specific project files.
https://github.com/NewhavenDisplay/EVE2-TFT-Modules
Click the ‘Clone or download’ drop-down, then click ‘Download ZIP’ and the browser will download the
EVE2 TFT Module library to your computer.
Un-zip the folder and rename it “EVE2-TFT-Modules”make sure to place the package into a desired
project folder and open the sketch file in the project folder to use one of the examples.

Application Sketch Test
IMPORTANT NOTE: Due to the current limitations of the USB input on the Arduino, whenever
connecting the Arduino to your computer and/or uploading code with an EVE2 TFT Module
connected to it, a DC power supply should always be connected to the Arduino’s DC input in
addition to the USB input con nection.
The example named ‘FT_App_Sketch’ demonstrates interactive sketching by utilizing the FT81x’s built -
in sketch, slider & button commands.
Select this example and upload it to your Arduino. When the Arduino restarts, you should see the
following:

Compatible Arduinos
The NHD-FT81x-SHIELD is compatible with a wide range of Arduino and Arduino clones, however there are some which
are not compatible. The NHD-FT81x-SHIELD requires 5V to be supplied from the Arduino itself, and some Arduino clones,
specifically 3.3V versions such as the Arduino Pro 3.3V, feature 3.3V on the pin typically specified as being 5V. These 3.3V
varieties are not compatible as 5V is required for the NHD-FT81x-SHIELD.
Known compatible Arduinos for the NHD-FT81x-SHIELD:
Uno
NerO
Leonardo
Mega 2560
