This little 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 a 1.44" 128x128 display, but has 4x as many pixels and looks great at any angle. Weve seen displays of this calibre used in smartwatches and small electronic devices but theyve 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 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 1.54" display has 240x240 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 the 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 coluor bitmaps from a FAT16/FAT32 formatted microSD card.
Please Note: The microSD card is not included
