This board comes with a micro SD card slot, a mini HDMI port, two micro USB ports (one for power, one for USB), and 512MB of RAM. It has a single-core 1 GHz processor chip, similar to the Pi A+ and B+. The version 1.3 of the Pi Zero. Version 1.3 is updated to include a camera port. The new Pi Zero camera port only works with a Raspberry Pi Zero Camera Cable. It DOES NOT work with a standard Raspberry Pi Camera cable.
Note: This is not the new Pi Zero W. This is the original Pi Zero v1 model, which does not include built-in Bluetooth and WiFi.
