NOTE: this is an older version of the board, and does not have the EYESPI connector. If you require a different version, please contact us!
This display is only 1.5" diagonal but has a high density 220 ppi, 240x240 pixel display with full-angle viewing. It looks a lot like Adafruit's 1.44" 128x128 display, but has 4x as many pixels and looks great at any angle. We've seen displays of this caliber used in smartwatches and small electronic devices but they've always been MIPI interface. Finally, we found one that is SPI and has a friendly display driver, so it works with any and all microcontrollers or microcomputers!
This little display breakout is the best way to add a small, colorful 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 1.54" display has 240x240 16-bit full color pixels and is an IPS display, so the color 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.
The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a 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 color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included.
Of course, Adafruit wouldn't just leave you with a datasheet and a "good luck!" - they'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 but can be easily ported to your favorite microcontroller!

Revision History:
-
As of July 24, 2019 we've changed the TFT used to be one that is more durable and also exposed the TE pin. The shape has also changed to accommodate the different TFT module, and the pinout has shifted to add the TE pin. Code usage is identical.
