hashboard tester tool

[jbates58]

Hi all

I have some s19pro units that are having issues with the haahboards. Some are temp sensor related, and some are not detecting asic chips.

I'm looking to buy a tester to test them to assist in identifying where the issues lie.

I have been looking at units like the picoBT,  k8, k9, STasic and others from zeus and other sellers online.

But im not sure what unit to get. Can I please get some guidance on what units are good and why.

Many thanks.
