+Models with the H suffix have header pins pre-soldered to the GPIO header. Models that lack the H suffix do not come with header pins attached to the GPIO header; the user must solder pins manually or attach a third-party pin kit.
+All Zero models have the following connectivity:
+  *     a microSD card slot
+  *     a CSI camera port (version 1.3 of the original Zero introduced this port)
+  *     a mini HDMI port
