 ====== Powering Vizy ======
-Powering Vizy is typically done by plugging in the AC-DC power adapter that comes with Vizy into Vizy's power input connector.  The power adapter supplies 12V at 2.5A.  The [[wiki:poe_getting_started|PoE adapter]] is a popular way to power Vizy as well.  But Vizy can be powered by other means as well.

 ===== Powering Vizy through the power input connector =====
+{{wiki:image_441.jpg?600}}
   * Vizy's power input connector can accept between 7.5V and 18V.
   * The input voltage dictates the voltage available at the [[wiki:pinouts|12V output]].
-  * It is recommended that Vizy's power supply not be less than 15W.
+  * It is recommended that Vizy's power supply not be rated for less than 15W of power.
   * Vizy's internal 5V switching power supply can supply up to 6A and operates at 90% efficiency.  The 5V supply is used to power the Raspberry Pi, the [[wiki:pinouts|5V output]], and the USB ports.  The sum of all these currents should not exceed 6A.
   * The power input connector is reverse-polarity protected.
+  * The power input connector is compatible with a [[https://www.digikey.com/en/products/detail/cui-devices/PP3-002C/992138|3.5mm outer diameter barrel connector with 1.1mm inner diameter]]
 ===== Powering Vizy through the USB-C connector =====
-You can power Vizy with a 5V supply through the USB-C connector.  This is useful if you want to use a [[https://bestreviews.com/electronics/chargers/best-portable-chargers|portable charger]] to power Vizy via battery.  (Portable chargers output 5V through a USB port and have large battery capacity.)

   * The 5V supply should be at least 4.8V and not exceed 5.25V.
   * The USB-C cable should have a high current capacity.
   * When using a 5V supply, the [[wiki:pinouts|12V output]] won't be available and should not be used.
-  * The button will no longer control power to Vizy.  Vizy will come on as soon as you plug it into the 5V supply.
+  * The button will no longer control power to Vizy.  Vizy will power on as soon as you plug in the 5V supply.
   * You can still do a safe shut-down of Vizy by holding the button until the Raspberry Pi shuts down, indicated by the beep. You can then unplug the 5V supply from the USB-C port.
   * All other aspects of Vizy will function normally.

 ===== Powering Vizy through the I/O connector =====
-You can also power Vizy through the I/O connector, which can be convenient if you want to reduce the things plugging into your Vizy, and you don't mind giving up the [[wiki:pinouts|12V output]] (the 12V output is designed to also be a power input.)  To power Vizy through the [[wiki:pinouts|I/O connector]] hook the negative side of the supply to one of the Ground pins (pin 1 or 8) and the positive side to the 12V output (pin 2).  The same conditions apply to this method as apply to [[wiki:powering_vizy#powering-vizy-through-the-power-input-connector|powering Vizy through the power input connector]] including reverse-polarity protection.
+{{wiki:image_443.jpg?600}}
+You can also power Vizy through the I/O connector, which can be convenient since the [[wiki:pinouts|I/O connector]] terminal blocks are easy to use.  The disadvantage is that you lose the [[wiki:pinouts|12V output]] for the time being (the 12V output is designed to also be a power input.)  To power Vizy through the [[wiki:pinouts|I/O connector]] hook the negative side of the supply to one of the Ground pins (pin 1 or 8) and the positive side to the 12V output (pin 2).  The same conditions apply to this method as apply to powering Vizy through the power input connector, including reverse-polarity protection.
+For example, if you have a 12V battery or power source, you can easily wire it into Vizy's I/O connector and be up and running quickly.
