This is a general LCD display Module from Waveshare with a TFT screen, 1.54inch diagonal, 240X240 resolution, and embedded controller ST7789 communicating via SPI interface.
This lovely little display breakout is the best way to add a small, colorful, and bright display to any project. Even a very small one with low memory and few pins available!
And the 1.54 Inch SPI 240X240 TFT LCD Display Module will always come with the same driver chip so there are no worries that your code will not work from one to the other.
The 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.
