Tardigrades (), known colloquially as water bears or moss piglets, are a phylum of eight-legged segmented micro-animals.

Johann August Ephraim Goeze originally named the tardigrade "Kleiner Wasserbär", meaning "little water-bear" in German (today, they are often referred to in German as "Bärtierchen" or "little bear-animal").

Tardigrades lack several Hox genes and a large intermediate region of the body axis. In insects, this corresponds to the entire thorax and the abdomen. Practically the whole body, except for the last pair of legs, is made up of just the segments that are homologous to the head region in arthropods.

Tardigrades are oviparous, and fertilization is usually external. Mating occurs during the molt with the eggs being laid inside the shed cuticle of the female and then covered with sperm.

The Raspberry Pi Zero W 2 uses the RP3A0-AU CPU, a 1 GHz 64 bit ARM Cortex A53, on 512MB of SDRAM. Documentation states this "system-on-package" is a Broadcom BCM2710A1 package, using a BCM2837 Broadcom chip as core, which is an ARM v8 quad-core. The Raspberry Pi 3 also uses the BCM2837, but clocked at 1.2 GHz.
