The Things Uno: Is there updated documentation?

Is there updated documentation available of the Things UNO?
The only documentation on the board I found so far is the beta release documentation. And that version is not the current version.

The only documentation on the board I found so far is the beta release documentation.

Is this what you’re referring to?

• https://www.thethingsnetwork.org/docs/devices/uno/

As an aside, I wonder if this is just a production error, or a design error:

@gmos

In the new version a series diode was used from the + (center) connection of the barrel connector to the input pin of the regulator. More friendly than shorting out the power at the cost of a small voltage drop.

However, on both of my boards the diode polarity is still as in the old version. Mening it just blocks all current now.

Only fix seems to be to solder it out and back with the polarity swapped.

Thanks a lot @arjanvanb for giving a pointer to the hardware specification. A brief look at the schematic shows that it is indeed a production error, not a design error.

@arjanvanb Thanks for pointing out. I got confused by the way it is organised.
