Rctimer MAVLink-OSD V2.2 For APM/PX4/PIXHAWK/Multwii/CF/OP

MAVLink-OSD is an Arduino based project and it is fully compatible with original MinimOSD.
This board can be used for all APM/PX4/PIXHAWK/Multwii/CLEANFLIGHT/OPENPILOT.
MAVLink-OSD with switching DC/DC stepdown powersupply to maximize efficiency on power system. No more heating probrem when using this OSD board. It can be only use two way power source.
MAVLink-OSD supported 3DRobotics original/ MinimOSD-Extra / rush-osd-development / minoposd /MWOSD firmware. 
Used for Multiwii with rush-osd-development firmware, four solder pads on the bottom side provide RSSI/voltage/current detetion. 
Schematics https://code.google.com/p/rush-osd-development/wiki/Hardware_Mods
Pad1: RSSI from receiver
Pad2: Video voltage
Pad3: Current sensor
Pad4: Main voltage
Using CC3D with minoposd firmware, Pad5/Pad6 used for voltage/current detetion.

Default firmware is 3DR original.
