This little module was liberated from a Canon wifi enabled printer that decided not to work anymore. It appears to bear the label "Product Number: K30306" at the upper left, which naturally was the first target for a thorough googling.. as were all the other numbers that looked remotely like part IDs. Sadly this did not yield the expected results.
Probing the connector on the printer's motherboard did not reveal any obvious power rails; apparently this printer doesn't turn on the wifi unless it's happy, i.e., not generating a terminal error code. If I were to speculate, I'd guess that the two twisted pairs might be USB and the 5th wire a special line for powering the RF sections.
Hopefully someone has run across this module or something like it before and can shed some light on how to make use of it. Fwiw, the printer was a Canon pixma mx860.
