In this article we describe briefly the Beaglebone Black development board. What said is applicable also to its derivatives (Green, Enhanced) for most of the information
From the above link there is a comparison chart between the various models.
The card is the result of an Open Source project with all its elements distributed on site

From the link
there is a complete description of all the features and sofware compatibility. The System Reference Document, available as a link in the site mentioned above, can be downloaded from the link
The card being Opensource and with many outputs and built-in controls lends itself very well to prototyping of IOT systems, Automation, Home Automation. The hardware functionality expansion can be executed by the usage of expansion cards called Capes
The main linux distribution for the BeagleBone Black card is Debian. On the Debian distribution for BeagleBone it is also available Cloud9
that allows you to interact easily with the hardware on the BeagleBone Black. In subsequent articles we describe the installation, creation of the image and various uses of the card.
Here is the link to the software and hardware features of the card; in particular the page shows the input/outpuy pin of the BeagleBone Black
The card can be purchased by following the links listed on the website
from online retailers or electronics stores.
