We've been looking for a display like this for a long time - it's so small only 1.14" diagonal but has a high density 260 PPI, 240x135 pixel display with full-angle viewing. It looks a lot like our 0.96" 160x80 display but has 2.5x as many pixels. We've seen displays of this calibre used in smartwatches and small electronic devices but they've always been MIPI interfaces. Finally, we found one that is SPI and has a friendly display driver, so it works with any and all microcontrollers or microcomputers!
This lovely little display breakout is the best way to add a small, colourful and very bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! The 1.14" display has 240x135 16-bit full-colour pixels and is an IPS display, so the colour looks great up to 80 degrees off-axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and our Arduino library supports it well.
Our breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as an ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. We also had a little space so we placed a microSD card holder so you can easily load full colour bitmaps from a FAT16/FAT32 formatted microSD card. The MicroSD card is not included.
Of course, we wouldn't just leave you with a datasheet and a "good luck!" - we've written a full open-source graphics library that can draw pixels, lines, rectangles, circles, text and bitmaps as well as example code and a wiring tutorial. The code is written for Arduino IDE but can be easily ported to your favourite microcontroller!
