Power Line Communication (PLC) is a technology that exchanges data via the AC electric power line. Mamba is a shield that lets your Arduino get access to this convenient home automation network. It’s compatible with Arduino DUO and UNO and can work under 110/240V, 50/60Hz. Mamba communicates with Arduino via SPI interface. We included a sample code here to show you how to implement the bridge between two nodes as a quick start.
