3.5 Inch 320x480 TFT LCD Module RGB888 + SPI + MCU Interface with CTP - VXT350QHI-37C
Victronix 3.5'' 320×480 Capacitive Touch TFT Module offers 300 cd/m² brightness and an 80-degree viewing angle in all directions ensure vivid imagery. Secondly, it supports seamless compatibility with RGB888 (24-bit), SPI (3/4-line), MCU parallel interfaces for flexible integration, and offers a capacitive touch controller (I²C interface: SCL/SDA/INT/RST) for responsive interaction, and a 6S-LEDs white backlight with a lifetime of 50,000 hours, ensuring its long-term usability in various industrial applications. Additionally, it complies with RoHS standards and successfully passes rigorous reliability tests, including 96H high/low temperature operation/storage, temperature cycling, and 60°C/90 % RH humidity. This product operates efficiently in extreme temperatures ranging from -20°C to +70°C and can withstand severe storage conditions from -30°C to +80°C. This 3.5 inch TFT module from Victronix is designed for Industrial HMIs, medical devices, portable instruments, and IoT applications that demand durability, touch interactivity, and vivid visuals.
