I am trying to power the Omega 2 without buying a dock. I know the input is 3.3V and 200mA.
This is what I am planning to do:
Purchase this USB step down - http://www.ebay.com/itm/3-in-1-DC-DC-USB-5V-to-3-3V-Step-Down-Buck-Module-LED-Motor-CPLD-ARM-AVR-Arduino-/231360476318
Solder the ground prong of the step down to the ground pin on the Omega.
Then Solder the 3.3V prong of the step down to the input pin on the Omega.
Finally, Plug the USB step down into a 5V 500mA wall charger.
My question is, will this work correctly?
