internal dc to dc supply only and requires an external 12v 4A adapter (Not included)
Just open up your unit, unplug the old supply, and plug in the new one, and sit the new input jack in the rear.
This supply provides up the 3.5a on +5v, so plenty for powering your sidecar devices (TIPI/SPEECH ETC)
Open source project, the info can be found at the github page.
