Am I reading this right? The "Trinket Pro" can take up to 16V input.
Can the UNO do this?
If so this solves supply issues for my project. I can use one 12V wall supply:)
16V input

Re: 16V input
Input Voltage (recommended) 7-12V
Input Voltage (limits) 6-20V
The power source is selected automatically.
External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.
The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.
so yes you can use 12vdc adapter

Re: 16V input
There's one point worth clarifying:
The 6v-20v limits apply to power supplies connected through the DC barrel jack. Those are the limits of its onboard voltage regulator.
The GPIO pins are limited to 0v-5v. Connecting 16v to one of those will probably kill the chip.
