Infineon have announced two shields for the Arduino development environment. The RGB LED Lighting Shield (shown left) provides three independent output channels with a DC/DC LED driver stage to give flicker-free control of multicolor LEDs. It is fitted with an XMC1202 microcontroller using a Brightness Color Control Unit (BCCU) to help off-load time-critical events from the Arduino processor. The Shield can be expanded by adding an optional isolated DMX512 interface for stage lighting control and audio nodes or a 24 GHz radar sensor for motion detection.
