4.3 All in One UART TFT, UART TFT LCD (RTP) - RFE43DM-EIW-DRS

4.3 All in One SPI / UART TFT LCD with Rresistive Touch Panel

Model No. RFE43DM-EIW-DRS

The M-series is also named “Clever System”, that is, smart TFT display introduced by Raystar. This is an all-in-one module integrated with controller board and built-in controller IC PIC24. The display comes with a PCB, metal frame and 4 screw holes allowing for easy mounting. The feature of M series TFT designed by our R&D team is that the process of displaying an image is simplified, users only need to send a command to the module and can display the content they require. Therefore, M series helps to cut down on time of development and is user-friendly for many. This series has different interfaces for customers to choose from, including UART (default) and SPI.

RFE43DM-EIW-DRS is one of the models in our M series--- 4.3-inch color TFT-LCD display module with Resistive touch panel (RTP). The resolution of this module is 480x272 pixels with aspect ratio 4:3, contrast ratio 500:1 (typical value), and brightness 500 cd/m2. LCM voltage ranges from 4.5 V~5.5V, typical value is 5V. Operating temperature covers from -20~+70℃, storage temperature range is from -30~+80℃.
