A miniature screen with an unusual shape
General LCD IPS display 1.28 '' 240 x 240 px - for Raspberry Pi and Arduino - round - Waveshare 19192 differs from other screens with a modern and aesthetic design, opening up wide possibilities to designers of small devices (e.g. portable), which due to the housing dimensions cannot use classic rectangular displays.
Communication via the 4-pin SPI interface allows you to easily connect the display to almost any microcontroller or minicomputer with logic levels of 3.3 V or 5 V. The built-in GC9A01 controller is responsible for communication.
Unique round display for various applications
Round displays are associated almost exclusively with smart watches, but their range of applications can be successfully extended to any other device that requires a small screen to display colorful graphics and text.
The round General LCD IPS 1.28 '' 240 x 240 px Waveshare 19192 display can be successfully used as a local Raspberry Pi or Arduino display in both amateur and commercial projects. It will work perfectly in the construction of your own smartwatch, a stylish audio player or a futuristic portable meter (e.g. a voltmeter or a tester of electronic components).
