Hello, I am working on an Arduino Quadcopter on Multiwii platform but the GUI can't recognise my 3.3v Arduino pro mini
where as the GUI recognises the 5v pro mini board
But I want to use 3.3v board so that I can power it directly with 3.7v lipo battery.
On YouTube, everyone where using the 5v Arduino pro mini board to build a drone thats why I don't have any idea if the GUI supports 3.3v Arduino pro mini 
.... otherwise I have to use the step up power module to increase the voltage to 5v and use the Arduino pro mini 5v/16Mhz board
