Hello guys and girls,
Just out of curiosity I opened my Pokitto to check things out and then I realized this:
Can someone tell me what this part Is for?
Thanks in advance.
Greetings
Peter

It appears to be a āLow Dropout Regulatorā, but I have no clue what that means.
I believe the upper value is the part id and the lower value is the date stamp (āQā usually means āquarterā).
It looks like itās eaither broken off or the soldering machine didnāt put it on correctly, but itās hard to tell.
Summoning @jonne.

For me it looks like it was misplaced by the machine, the one leg doesnāt even have solder on it 
so I am a bit afraid that my new pokitto will die a premature death (only 1 day old )

I think it might be fixable, but it would require some soldering, which is a skill not everyone has,
and this probably wouldnāt be the best thing to learn on.
Normally Iād suggest that if you knew someone who was good at soldering,
then maybe you could ask them to have a go at it,
but I donāt know if that would void your warranty or not.
We will have to wait to see what @jonne says about the issue.
(For the record: I may be a moderator but Iām not actually employed by Pokitto Oy,
so I canāt make decisions about arranging replacement boards.)

I havenāt had time to look at the schematics yet.
If its the low dropout LDO, its the LDO for the real-time clock.
Most likely got knocked out of place before entering reflow oven
Edit: this is the first instance of this particular problem and naturally I am sending you a new board
Meanwhile, your Pokitto is otherwise fully operational, because the effect of the LDO is to supply power to the RTC when the device is in shutdown. Only thing you will notice is the RTC will lose time
