Raspberry Pi Foundation sells tiny, affordable single-board computers like the $5 Pi Zero, $25 Pi 1 Model A+, and $35 Pi 2 Model B in order to increase the number of children who learn computer programming and apply to study computer science in university. As an educational charity, the Raspberry Pi's price, portability, and goal of teaching programming give it an advantage over competitors like the Pine A64, Galileo, and upcoming Arduino Tre, despite those alternatives having more powerful specs in some cases. The Raspberry Pi is positioned to remain popular due to its large community and continued product improvements like the Raspberry Pi 3.
