This 1.9′ display module from Waveshare features a bright and colourful IPS panel with a 170×320 resolution and 262K colours.
The 4-wire SPI interface allows this display to be used with popular development boards such as the Arduino Uno and Raspberry Pi in C and Python, both of which have code examples in the online wiki, and reduces the number of GPIO pins used.
The display comes with a matching 8-pin cable with female headers to connect to your microcontroller.
