Admatec presents the C-Berry module as a supplement to the Rasberry PI computer. With this add-on module, users can display their application independently of a monitor. In contrast to previous display extensions, the module is not operated via the integrated HDMI or VGA connection, but via SPI. According to the manufacturer, the power consumption of the entire system is so low that no additional power supply unit is required. The display has a resolution of 320 × 240 pixels and offers a brightness of 600 cd/m2 with contrast values >5000. The TFT display has a diagonal of 8.88 cm (3.5 inches). The integrated graphics controller 'RA8870' supports the drawing of simple geometric shapes (circle, rectangle, line).
