The XMC 3-channel RGB LED lighting shield from Infineon Technologies is an evaluation board compatible with Arduino as well as Infineon’s XMC1100 Boot Kit. It is designed to be easily configurable and combinable for different LED light engines and lamps, for fast prototyping and inexpensive evaluation of LED lighting applications.
The board uses a DC-DC buck topology and is able to drive up to three LED channels with constant current. The shield itself is powered by a programmable XMC 32-bit ARM MCU with embedded brightness colour control unit (BCCU, XMC1300 MCU series), for flicker-free LED dimming and colour control. The BCCU enables very low-cost but high-quality LED lighting solutions, with minimal user code.
The RGB LED lighting shield has also been designed to provide options for the evaluation of smooth, eye-friendly dimming, colour mixing for different topologies, and it can be extended with, for example, DALI/DMX or radar.
