Cluster stack and Pi5

Hi,

Just wondering if the new Pi5 will work in the cluster stack.  Form look the same but they are saying it will need more power.

I haven't got a Pi5 to check it physically fits, I'm still waiting for the pre-order like most people and it's probably going to be a while after that before I can get 5 to fully test with.

But, they say the peak power usage of the Pi 5 is 12W ( https://www.raspberrypi.com/news/introducing-raspberry-pi-5/ ) and others are seeing ~7.4W with stress tests (https://www.tomshardware.com/reviews/raspberry-pi-5 / https://www.jeffgeerling.com/blog/2023/overclocking-and-underclocking-raspberry-pi-5 )

The Cluster Stack is rated for 51W (5.1V*10A) so it depends where your usage fits - if it's at the stress-ng levels of 37W for five Pi 5 then it should power it without issue but if your usages is closer to the 60W for five Pi 5 then you're likely to see throttling.

Chris.
