We've been looking for a screen like this for a long time - it only has a 1.5" diagonal but has a high density of 220 ppi, 240x240 pixels with a wide angle display. It looks a lot like our 1.44" 128x128 screen, but it has 4x more pixels and it looks great from any angle. We have seen displays of this calibre used in smart watches and small electronic devices, but they have always been a MIPI interface. Finally, we found one that is SPI compatible and has a user-friendly display driver, so it works with all microcontrollers or microcomputers!

This pretty little display card is the best way to add a small colorful and very bright screen to any project. As the display uses 4 SPI wires to communicate and has its own addressable frame buffer per pixel, it can be used with any type of microcontroller. Even a very small one with little memory and few pins available! The 1.54" screen has 240x240 16-bit color pixels and is an IPS screen, so the color is very beautiful up to 80 degrees relative to the 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 a soldered TFT display (it uses a delicate flexible circuit connector) as well as a 3.3V regulator with very low voltage drop and a 3/5V level adapter so you can use it with 3.3V or 5V power and logic. We also had some space, so we placed a microSD card holder so you could easily load color bitmaps from a microSD card formatted FAT16/FAT32. The microSD card is not included.


Of course, we won't just leave you a technical sheet and a "good luck"! We have a complete open source graphics library that can draw pixels, lines, rectangles, circles, text and bitmaps as well as a sample code and wiring tutorial. The code is written for Arduino but can be easily ported to your favorite microcontroller!
