This adorable 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 types of microcontrollers, even those with limited memory and few available pins! The 1.44 - inch display offers 128x128 color pixels. Unlike the low - cost 'Nokia 6110' and similar CSTN LCD displays with poor color and slow refresh, this is a true TFT. The ST7735R TFT driver can show full 16 - bit color with our library code. The breakout comes with the TFT display soldered on via a delicate flex - circuit connector, an 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 microSD card (not included). We've developed a comprehensive open - source graphics library that can draw pixels, lines, rectangles, circles, text, and bitmaps. Example code and a wiring tutorial are also provided. The code is written for Arduino but can be easily adapted to your preferred microcontroller.
Using this Adafruit display is easy. First, connect it to your microcontroller following the wiring tutorial. You can power it with either 3.3V or 5V, thanks to the built - in level shifter. If you want to show full - color bitmaps, insert a FAT16/FAT32 formatted microSD card into the holder. To draw graphics, use the open - source library we've provided. You can write code similar to the Arduino examples and then adapt it to your microcontroller. When handling the display, be gentle with the flex - circuit connector as it's delicate. Avoid exposing it to extreme temperatures or humidity. To keep it in good condition, store it in a dry and clean place when not in use. And don't forget, if you run into any issues, refer to the documentation or reach out to our support team.
