The raspberry header is the key to its ability to interface with the real world. The pi either uses a 40 pin or 26 pin depending on the model and it is important to understand how those pins are arranged and labelled. On the raspberry pi model 3b the hardware based serial uart device dev ttyama0 has been re purposed to communicate with the the built in bluetooth modem and is no longer mapped to the serial rx tx pins on the gpio header. The gpio header provides the following power and interface options.
