1.8 Color TFT LCD display with MicroSD Card Breakout [ST7735R]

This charming small display breakout is an excellent choice for adding a compact, vivid, and bright display to any project. Using 4-wire SPI for communication and featuring its own pixel-addressable frame buffer, it's compatible with all kinds of microcontrollers, even those with limited memory and pins. The 1.8-inch display boasts 128x160 color pixels. Unlike low-cost CSTN LCDs like the 'Nokia 6110' with poor color and slow refresh, this is a true TFT. The ST7735R driver can display full 18-bit color (262,144 shades!). The same driver chip is used for every LCD, so you don't have to worry about code compatibility. The breakout has the TFT display soldered on via a delicate flex-circuit connector, along with a ultra-low-dropout 3.3V regulator and a 3/5V level shifter, allowing use with 3.3V or 5V power and logic. There's also a microSD card holder for easily loading full-color bitmaps from a FAT16/FAT32 formatted card (microSD card not included). We've provided a full open-source graphics library with example code and a wiring tutorial. The code is for Arduino but can be easily adapted to your preferred microcontroller.

Using this 1.8-inch color TFT LCD display is a breeze. First, connect it to your microcontroller following the wiring tutorial provided. You can use either 3.3V or 5V power and logic thanks to the built-in regulator and level shifter. If you want to show full-color bitmaps, insert a FAT16/FAT32 formatted microSD card into the holder. The open-source graphics library makes it easy to draw pixels, lines, rectangles, circles, text, and bitmaps. Just use the example code as a starting point and adapt it to your needs. When handling the display, be careful with the delicate flex-circuit connector. Avoid bending it too much. Keep the display clean by gently wiping it with a soft, dry cloth. If you're not using the microSD card holder, keep it covered to prevent dust from getting in. And remember, the microSD card is not included, so you'll need to get one separately.
