Introducing the Raspberry Pi Zero board
The Raspberry Pi Zero is a board that was introduced in 2015, and the goal was to make a low-cost ($5), small-format board with most of the functionalities of the original Raspberry Pi board.
The following is an image of the Zero board:
In the center of the board, you will find the same System-on-a-Chip (SoC) as the original Raspberry Pi board, with a 1-GHz single-core processor, 512 MB of RAM, and a graphical processing unit.
The board has several inputs and outputs, like the 40-pin GPIO connector that we will use through this whole book to connect the board to sensors and other components.
There are also two USB ports (one for power, one for communication), one mini-HDMI port, and one SD card slot to put the operating system and other files in.
The power consumption of the board was also reduced compared to the first board, going from 1.5W to 0.8W.
