Hello,
I just received my SX KeyRing this morning and had a few questions about it:

1 - It appears that the silkscreen is backwards where the SX-Key plugs in.  I can follow the traces and used an ohm meter to confirm that I should not reference the silkscreen and the component side of the SX-Key should be up instead of what the silkscreen shows.

2 - The connector looks like it is center + and the outside GND.  Can someone confirm the specs for the power adapter?

3 - Was there a datasheet online just for the SX KeyRing?  There no longer seems to be any reference on the Parallax site for it.

Hi Robert;
1.  You are absolutely correct.

2.  Correct again. I use a 9-ish volt center positive wall wart. Works fine.

3.  Can't help you here.

Cheers,
Peter (pjv)
