1.28" Round Touchscreen LCD Display Module

Don't be a square, be round! Treat your next project to one of these round, touchscreen LCD displays for an impressive interface to menus, on-screen buttons and more. This awesome 1.28" touchscreen display features a 240x240 resolution with 65K RGB colours for a clear and colourful interface. Mix that with the SPI and I2C communication and you've got a great-looking touch display for your project without hogging all of your GPIO pins. You can use an array of development boards with this display, with demo code provided in the online wiki for Raspberry Pi, Raspberry Pi Pico, Arduino and STM32. The display comes complete with a GH1.25 13-pin cable which has female headers ready to connect to your microcontroller. We also offer a non-touch version, a more affordable option for projects that don't require a touchscreen interface. Features
