7-inch HDMI 800x480 TFT LCD Module with PCAP - RFF70VD3-1IW-DHG - Raystar

HDMI 800x480 TFT LCD Display with PCAP (only DVI signal) (TFP401 IC)

Model No. RFF70VD3-1IW-DHG

The RFF70VD3-1IW-DHG is a 7-inch HDMI 800x480 TFT LCD display designed to deliver stable image output with vibrant color performance. It supports an HDMI interface and integrates a projected capacitive (PCAP) touchscreen via USB. The touchscreen incorporates the ILI2130 IC to enable single-touch, dual-touch, and multi-touch operation.

This HDMI 800x480 TFT LCD module provides a typical brightness of 350 cd/m² and a contrast ratio of 800:1. The LCM operates at a voltage range of 4.9V to 5.1V (typical 5V) and is specified for reliable operation from –20℃ to +70℃. Storage temperature is rated from –30℃ to +80℃ to support industrial and embedded system requirements.

If you have further questions about this HDMI 800x480 TFT LCD display, please feel free to contact our sales team. We are ready to support your project evaluation and integration needs.

★RFF70VD3-1IW-DHG comes equipped with a 40-pin header connector, making it compatible with systems such as the Raspberry Pi 3B+ and Raspberry Pi 4B. However, for Raspberry Pi 4 users, please note that the interface is limited to micro HDMI, requiring the use of a “Micro HDMI to HDMI” cable for proper connection.
★RFF70VD3-1IW-DHG does not include an onboard connector and does not support Raspberry Pi integration.
