ClusterHAT hardware versions

[Peter F]

I bought a ClusterHAT a couple of years ago and it's languished in my projects box for too long.

The version number of my board is v1.1.

Now I think I've found a good (or potentionally good) use for it, I see that there have been several versions produced.

Is there a source of information on the differences between the various models, please?

Is there anything I should be aware of when using the latest setup information and images when configuring my cluster based on my v1.1 board?

Many thanks,

Peter

Hi, 

I bought a ClusterHAT a couple of years ago and it's languished in my projects box for too long.

The version number of my board is v1.1.

Is there a source of information on the differences between the various models, please?

In https://youtu.be/Xitd5xWP8Yo I go through the different versions and point out the differences.

The biggest difference with the newer boards is the addition of the I2C I/O expander from 2.0 which allowed the Pi Zero to remain powered on whilst rebooting the controller Pi. On your 1.1 board rebooting the controller will power off the Pi Zeros so these should be shutdown first.

 

Is there anything I should be aware of when using the latest setup information and images when configuring my cluster based on my v1.1 board?

 The current Cluster HAT images should work OK with all revisions of the board.

Chris.
