Problem with LM3 V2

[buuuudzik]

If I were you I wouldn't be looking on the standard shop micro SD only something more robust. The best are the SLC cards like this for example https://uk.rs-online.com/web/p/micro-sd-cards/1874668/

I know, but I don't have guarantee which card will work especially with old devices before trying. In this time firstly I've tried most expensive 32GB cards in Media Markt but they were not helpful and secondly I've try cheaper because old technology will be cheaper and this was half correct

On my customers installations I have only 2 old devices where this could be a problem in future.

SD cards are very messful for me, it is not possible to easily compare them. With these 3 types of cards which I've used at this time all had theoretically same specification, but only one work with LMReactor3V2.

Thank you for suggestion of specific card type and model. It is very helpful and I will probably use it next time. Only one question: I should use min. 4GB version?
