But it comes fixed at that voltage, you can't change it to use it for some other project later.
Also: I can't get the web-site listed on that board to respond.
Not a good sign of a supplier you can trust.
As palbeda posted above, go with the one we recommend.
That one can also be ordered pre-set to use the external reference pin to set a 1v8 level.
Note: The recommended board is Open Source Hardware, all of the files required to build it yourself are posted and licensed for re-use.

Hmm...
I don't recall if we have documented where to pick-up the 1v8 reference level on a PW-1 board.

Since the advent of the 5.6.x series firmware, we have had a lot of information posted here about adding the serial port to various models.
It looks like most of that newer information hasn't been indexed yet.
Hint:
**anybody** can add to the Master Index, its a Wiki.
