The Raspberry Pi is a single computer board — developed to encourage and aid the teaching of programming and computing. It is also a fantastic starting point for the development of the Internet of Things (IoT) projects. The low cost and 'plug and play' nature of Pi makes for a board that is accessible to all and has numerous connectivity options. Compared to its predecessor, this has more processor speed, on-board connectivity, 2.5 A power supply. You will need the Official Raspberry Pi 3 Power Supply. The Pi 3 features a chip antenna where status LEDs were located previously. The status LEDs are still on the board, right next to the microSD card slot.
