No, but we have tested an inexpensive adapter that we can recommend.
POE Texas’ Adapter can be purchased directly at POETexas.com or from Amazon.
(Update) One of two of these POE adapters that we have been testing failed after 9 months.
Full disclosure: The failed while powering an alternative StingBox platform. The platform still works and the POE doesn’t.
But this isn’t a sufficient data set to say for certain that the power supply was the cause of its failure.  There are several other manufacturers on Amazon.
