Community

Strong communities have been formed around the most popular boards. They offer a range of software with drivers for the most widely used sensors. There are also some hardware initiatives that sell extensions for boards, enabling one to easily scale a device. Some of the major communities include the following:

• The Raspberry Pi Community (https://www.raspberrypi.org/community/)
• Arduino Forum (https://forum.arduino.cc/)

Following the links, you can find a lot of examples for different experience levels.
