Interface Description
(Capacitive Touch model shown above as reference)
Num.
Description
1)
(LED2) LED Indicator for Touch Resistive Touch models only
This is a Red LED that will blink slowly (once per second) if the RTP controller is powered ON, awake, and no touch is
detected. This LED will blink rapidly (5 times per second) if the RTP controller detects a touch.
2)
(LED4) LED Indicator for Touch Capacitive Touch models only
This is a Red LED that will illuminate when there is a touch sensed on the CTP.
3)
(LED3) LED Indicator for Power
This is a Green LED that will illuminate when DC power is supplied to the module.
4)
(CN3) DC Jack (Center-Positive), 2.00mm ID, 5.50mm OD
This is used to supply power to the display module. A DC power supply in the range of 5V 7.5V must be used.
The output current rating of the DC power supply should be at least the maximum Supply Current (IDD) listed in the Electrical
Characteristics section on the previous page.
5)
(CN4) Surface Mount Pin Header, 2.54mm pitch, for Backlight PWM
The pin labelled ‘PWM’ is connected directly to the LED driver’s CTRL pin (T.I. TPS61165). This is a multifunctional pin which
can be used for enable control, PWM, and digital dimming. A PWM frequency in the range of 5kHz 100kHz must be used.
6)
(CN2) Micro-USB (Type-B) Connector for Touch Touch Panel models only
This is to connect the Touch Panel of this module to a USB input to act as a USB-HID device.
7)
(LED1) LED Indicator for Video
This is a Blue LED that will illuminate when there is an active video signal detected.
8)
(CN1) HDMI (Type-A) Connector
This is a full-size HDMI connector meant to connect the HDMI source signal (Video only) to this module.
The on-board T.I. TFP401A HDMI/DVI Receiver does not scale video resolutions. Therefore, the output resolution of the
source must be 800x480 (WVGA). In most applications, this is automatically detected by the HDMI source.

Connecting with Windows/Windows Embedded
Connecting our HDMI TFT Modules to a Windows system is fully plug -and-play. Start by plugging in a
DC power supply in the range of 5 - 7.5V, with at least 1A of output current . The green LED near the
DC jack will illuminate when the board has power supplied to it. Next, connect the display to your
system via HDMI cable. Due to the on -board EDID, the display will be detected automatically and the
systems output resolution will set itself to 800x480.
For Touch Panel models, once the display is connected to the system via USB, Windows will
automatically detect and install the necessary drivers.
The above windo w is shown for the Capacitive Touch model. The Resistive Touch model will also install
automatica lly, however it will be labelled AR1100 HID -MOUSE instead of Newhaven Display.

Once Windows has finished installing the drivers, the device will show as Ready to use.
For reference, in Device Manager the USB-HID Touch device will show as below:

Connecting with Linux
Most Linux applications with an HDMI so urce will also be fully plug-and-play, however when using our
HDMI TFT Modules with the Raspberry Pi, the config.txt file on the Pis microSD card will need to be
slightly modified by the user.
The following highlighted lines need to be added in config.txt for proper display output:
# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details
# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1
# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16
# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720
# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0
# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2
# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4
# uncomment for composite PAL
#sdtv_mode=2
#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800
# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on
# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi
# Additional overlays and parameters are documented /boot/overlays/README
# Enable audio (loads snd_bcm2835)
dtparam=audio=on
