Raspberry Pi Zero

History

In May 2016, six months after the official release of Pi Zero, Raspberry Pi foundation launched 1.3 version of Pi Zero. The key feature was to support camera serial interface (CSI connector) which used to be equipped on high-end Raspberry Pi. Thus, Pi Zero began to be able to connect with cameras.

Raspberry foundation released Pi Zero W in February 2017. The whole design of Pi Zero W is similar to Pi Zero 1.3 but supports Wi-fi and Bluetooth. Wi-Fi supports IEEE 802.11n, and Bluetooth supports 4.x, including BLE (Bluetooth Low Energy).

Like Raspberry Pi 1, Raspberry Pi Zero and Zero W are built around the Broadcom BCM2835 SoC.
