Strange problem powering MiniTiouner v2.

The good module was from seller alltopnotch.

in light of the issues with these DC-DC boards, i'm wondering if its worth using pin headers and socketing this part.

Has anyone tried this version, it has a multi-turn pot which is preferable to me.

Last June I bought 10 boards from https://www.ebay.co.uk/itm/10-PCS-Mini- ... ctupt=true

Six have been used and all OK.

It's likely the sellers buy from the same factory so it's pot luck. For example I bought 3 x ADF4351 boards from different suppliers; they all had the same PLL fault.
