LCD Description
This compact 1.44-inch color active matrix TFT LCD Display features a square 128×128 resolution. Powered by the high-performance ST7735S controller, this robust module supports a high-speed SPI interface, making it an ideal choice for space-constrained applications such as wearables, IoT sensors, medical devices, and handheld instruments.
With an ultra-slim profile (2.50mm thickness) and a small footprint, it allows for effortless integration into compact hardware designs. The SPI serial bus significantly reduces the number of I/O ports required, simplifying the connection with popular microcontrollers like STM32, ESP32, or Arduino.
As a leading LCD factory in China, Hongcai provides reliable long-term supply, technical support, and flexible customization options (including backlight brightness and FPC adjustments). Contact us today for technical datasheets or bulk wholesale pricing for your next project.
