Compact Design with Precision Dimensions
Featuring a 1.77-inch TFT screen, this module offers a compact footprint (PCB: 55.70±0.2mm, TFT: 43.70±0.2mm) with precise hole positioning (32.40±0.2mm and 50.70±0.2mm) for seamless integration. The 128×3RGB×160 resolution ensures vivid visuals, while the 28.03mm (TFT A/A) and 35.04mm (TFT A/A) active areas balance clarity and space efficiency.
Versatile Connectivity & Robust Construction
Equipped with an SPI 3L/4L interface, the module supports flexible communication protocols. Its P2.54x7 (17.78mm) and P2.54x10 (25.40mm) pin headers enable easy wiring, while the 2.30mm pin header plastic height and φ2.00/φ3.50mm holes ensure secure mounting. The PCB thickness of 1.60mm adds durability for industrial applications.
Extreme Environment Adaptability
Operating Temp: -20℃ to +70℃ (TFT)
Storage Temp: -30℃ to +80℃
Designed for harsh conditions, this module withstands wide temperature ranges, making it ideal for outdoor devices, industrial controls, and consumer electronics.
High-Performance Visual Experience
Powered by the ST7735S driver IC, it delivers 850 cd/m² (Typ.) brightness with constant current testing for consistent illumination. The 12 O'Clock viewing direction (U45/D20/R45/L45) ensures optimal visibility from multiple angles, while the built-in backlight driver circuit simplifies system design.
