[ok2arm]

... problem was be on the output from CO2sensor, I found crack way on pcb, near output pin... Because was be read ok and sometimes not...

It should not happen but is impossible to say that it will not happen even with good quality PCB's -

If possible send me by PM a closeup picture of the damaged via.

And last problem is in RX unit, RX dont roll bettwen PM2,5 and PM10 as WD... Can you ask me, whitch part SW is for changing 2,5/10 ? On the LCD is just 2,5
Tnx

Well, this one is easy for me to answer
That feature wasn't implemented in the Pro2 PLUS RX software yet. It shows only the PM2.5 values, which are the ones used to compute AQI

Maybe it will be implemented on next release...

Not WX board, but on CO2 sensor, bettwen cower and soldering pin.... Your PCB is well !!.. Oki, maybee in future So also maybe idea options for autochanging custom pages, I like change 1 and 2 screen auto....

So now make some mechanical parts and post some foto..
Thank you and to Zdenek for solve some newbile problems !

Tnx Joe
