It bridged the gap between the original Pi and the Pi 3's built-in Wi-Fi.

The Pi 2 was the first quad-core Raspberry Pi, making it viable as a lightweight server.

It kept the $35 price while delivering enough CPUCentral processing unit — the primary chip that executes program instructions. for multi-threaded maker projects.
