Original Raspberry Pi Zero Board Camera Version 1.3 with 1GHz CPU 512MB RAM Linux OS 1080P HD video output

While the Raspberry Pi 2 marks the top end of the platform’s tech specs, the Pi Zero takes the opposite approach. This is, for all intents and purposes, an entry-level model that’s been reduced both in price and size (being three times smaller than the original Raspberry Pi 1 series).
