KMR-1.8 inch TFT LCD Module

The KMR-1.8 is a compact 1.8-inch full-color TFT LCD module designed to add a bright, pixel-addressable display to microcontroller projects. Built around the Sitronix ST7735S driver IC, it delivers a resolution of 128 × 160 pixels with 16-bit RGB color depth (65K colors) and a white LED backlight, producing clear graphics, text, and user interfaces in a small footprint. The module communicates over a 4-wire SPI interface, requiring only a few digital pins from the host controller, and operates from a 3.3V logic supply while tolerating 5V input levels when an onboard regulator is present. Its active display area measures 28.03mm × 35.04mm, and the PCB module measures 38.30mm × 62.48mm, making this KMR-1.8 TFT LCD module suitable for handheld instruments, data monitors, and embedded control panels. The display is supported by widely available Arduino libraries (including Adafruit-ST7735 and UTFT), and the onboard microSD card holder (on compatible variants) allows bitmap and font storage. With an operating temperature range of -10°C to +60°C, this 1.8 inch TFT display is well-suited to indoor electronics projects, prototyping, and educational demonstrations that require a reliable full color TFT display with straightforward SPI integration.

Application

1. Data monitoring and sensor reading displays in electronic projects.
2. Handheld instruments and portable devices requiring a compact graphical interface.
3. Medical display systems and diagnostic equipment with small-screen requirements.
4. DIY electronics and educational demonstrations of SPI communication and graphics.
5. Custom control panels and embedded user interfaces where a 128x160 SPI display is sufficient.
