LiFi Visible Light Communication Compatible for Raspberry Pi




RPI Li-Fi Shield is a plug-and-play evaluation board for developing a wide array of visible light communication applications in consumer, wearable, industrial, medical and Internet of Things (IoT). RPI Li-Fi Shield transfers data from one source to another through visible light without the flickering effect. Technically, 1‟s (LED on) and 0‟s (LED off) are modulated and then transmitted at very high speed.
