WF70GTIFGDHTV is a 7 inch medium-sized for HDMI signal TFT-LCD display, made of resolution 800x480 dots. This 7 inch TFT Display comes with a board which supports HDMI signal interface and a 40-pin connector on it; WF70GTIFGDHTV is designed to make Raspberry Pi usage become easily. This WF70GTIFGDHTV TFT display has a USB interface Resistive Touch screen overlay on TFT panel. Also the Capacitive Touch Panel is available for option. We designed a connector part no. WWHDMI-00# for option, the customers can use it to connect WF70GTIFGDHTV module with your Raspberry Pi directly. If customers do not require a 40-pin header connector on board, please choose WF70GTIFGDHT0.
You can simply use this medium-sized TFT display with your Raspberry Pi, and also you can use it as computer display with any device which supports HDMI signal output. This 7" TFT display is 800x480 resolutions, which is just enough to run most software, but still small enough that it can be used in portable or embedded projects without the bulk. Please note, this part no. WF70GTIFGDHTV does not include any HDMI connector or USB cable.
Part No. WWHDMI-00# (Optional component)
▪Support HDMI connector (Only DVI Signal) for TFT module and Raspberry Pi
WF70GTIFGDHTV#: 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 this series products.
WF70GTIFGDHTX#: with a 40-pin header connector on board, supports ahead of Raspberry Pi 3 version only.
WF70GTIFGDHT0#: without connector on board(do not support Raspberry Pi.
