Xadow - 1.54'' Touchscreen
If you have used or heard about Rephone, the world's first open source and modular phone, you will not be strange with the product we are going to talk about. Yes! The Xadow 1.54'' Touchscreen is right just the touchscreen that Rephone uses.
This TFT Display contains 240 x 240 pixels that can be controlled individually to display up to 262K colors. Above the display is a layer of a capacitive touchscreen, offering 29.4mm x 29.4mm active area at the center of the display. As a single touch screen, it can detect finger presses anywhere within the active area during normal operations. The TFT driver gets the ST7789S IC Driver inside with 2-bit data and 4-bit control serial interface while the capacitive touchscreen controller uses I2C.
We have few modifications to library of Xadow 1.54" Touchscreen. Please refer to the Notice section for detail information.

- The product is not as tough as it looks, so try to use it in a stable environment as an abrupt variation of temperature and humidity may cause malfunction of the panel.
- Try to keep the panel surface clean and avoid any adhesive applied on the surface, if you have to clean the screen, we recommend you to use clean and soft cloth with neutral detergent or isopropyl alcohol.

We’ve been looking for a better place where our backers (RePhone Users) can sit together, warmly and comfortably, have conversations about RePhone, discuss technical problems, share ideas/projects, and give feedback on the modules’ development in the future. And then here we go, the RePhone Community.
Now join us in the RePhone Community! Together we seek answers, make interesting stuff, care about each other, and share our experiences.
