DESCRIPTION

WF70A2TIFGDHGV is a 7 inch supporting HDMI (Only DVI) signal TFT-LCD module with Projected Capacitive Touch Panel (PCAP); it’s made of WVGA 800x480 resolution. WF70A2TIFGDHGV comes with a control board which supports HDMI signal interface and a 40-pin GPIO connector on board; it is designed to make Raspberry Pi usage become easily. This display has a USB interface Capacitive Touch Screen overlay on TFT panel. We designed a connector (P/N WWHDMI-00#) and USB cable (P/N OTP1XXXXXXXXXXXX0155) for option, the customers can use it to connect WF70A2TIFGDHGV module with your Raspberry Pi directly. Please note, this part no. WF70A2TIFGDHGV does not include any HDMI connector or USB cable.

WF70A2TIFGDHGV is built in with TFP401 Controller IC convert signal to support HDMI (Only DVI) signal interface, as to the PCAP (CTP) IC is ILI2130, it supports USB interface. The supply voltage for LCM (VDD) is typical value 5V. It is featured with Glare surface glass, view direction 12 o'clock, gray scale inversion 6 o'clock.

Part No. WWHDMI-00

Part No. WWHDMI-00# (Optional component)
▪Support HDMI connector (Only DVI Signal) for TFT module and Raspberry Pi

WF70A2TIFGDHGV#: with a 40-pin header connector on board, supports up to Raspberry Raspberry Pi 3B+ (contain Pi 4B) version.  If customers choose Raspberry Pi 4 version, please note the interface is Micro HDMI; customers need to use the Micro HDMI to HDMI cable for Winstar this series products.
WF70A2TIFGDHG0#: without connector on board(do not support Raspberry Pi).
