Relay backwards wiring

Grove is a modulated, ready-to-use tool set.
Much like Lego, it takes a building block approach to assembling electronics.

Relay backwards wiring

The relay module v1.2 seems to be wired incorrectly for the standard Grove plug.

BK --> sig
RD --> N/C
WT --> vcc
YL --> gnd

What's going here, and how is it that could possibly work with other standard Grove modules?

Just figured out what is wrong: The relay I happened to use WAS ASSEMBLED INCORRECTLY, and the error was not caught by any QA.

I caught this by comparing to another relay. I tried to upload a photo, but your forum gave me the error, 'Could not upload attachment to ./files/14935_ff9f92c0138a89789684f56cd94c2145.'

The plug was soldiered on backwards.
