WF70A2TIFGDHTV is a 7 inch Resistive Touch Panel TFT-LCD module which supports HDMI (Only DVI) signal; its resolution is made of WVGA 800x480 dots. WF70A2TIFGDHTV comes with a control board which supports HDMI (Only DVI) 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 Resistive 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 WF70A2TIFGDHTV module with your Raspberry Pi directly. Please note, this part no. WF70A2TIFGDHTV does not include any HDMI connector or USB cable.
WF70A2TIFGDHTV is built in with TFP401 Controller IC convert signal to support HDMI (Only DVI) signal interface. The supply voltage for LCM (VDD) is typical value 5V. It is featured with Anti-Glare surface glass, view direction 12 o'clock, gray scale inversion 6 o'clock, aspect ratio 16:9.
Part No. WWHDMI-00# (Optional component)
▪Support HDMI connector (Only DVI Signal) for TFT module and Raspberry Pi
WF70A2TIFGDHTV#: with a 40-pin header connector on board, supports up to 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.
WF70A2TIFGDHT0#: without connector on board(do not support Raspberry Pi).
