This is what a cluster board with 16 Raspberry Pi Zero’s looks like

It is a $5 affordable computer which was launched in November 2015.

However what happens when you pool the computational power of 16 Raspberry Pi Zeros together.

This is whatIdein, a Japanese startup did.

Idein made a PiZero Cluster board which has 32 micro USB ports for power and data.

Two for each Raspberry Pi Zero board, 16 USB throw in A ports, and 16 Ethernet interfaces.

So we need many Pis for the development and tests.

Since we will use Pis GPU for image processing, deep learning, etc.

We need real Pis but not just Linux machines.

This is what the final product looks like as announced by Nakamura on Twitter
