Description
WF35RTIACDNNB is a 3.5-inch standard 320240 TFT-LCD module with a diagonal size and a resolution of QVGA 320x240 pixels. It incorporates the SSD2119 IC, which integrates the functions of both the controller and driver IC. This module supports RGB, SPI, and MCU interfaces, with a supply voltage (VCI) ranging from 2.5V to 3.6V. It features an Anti-Glare surface panel, with a View Direction at 12 o'clock and Gray scale inversion at 6 o'clock, maintaining an aspect ratio of 4:3.
The WF35RTIACDNNB TFT-LCD module is designed in landscape mode with a brightness rating of 400 nits (typical value). The power supply voltage ranges from 2.5V to 3.6V, with a typical value of 3.0V. It is capable of operating within temperatures ranging from -20℃ to +70℃, while its storage temperatures range from -30℃ to +80℃.
