New V2.1 MAVLink-OSD is an Arduino based project and it is fully compatible with original MinimOSD.

MAVLink-OSD full support for rush-osd firmware to support the MWC flight control, can be used to battery voltage detection, video voltage detection, RSSI and current detection...(current detection need bring you own sensor).

Rush-OSD firmware supports the above functional schematics:

MAVLink-OSD with switching DC/DC stepdown powersupply to maximize efficiency on power system. No more heating problems when using this OSD board. It can be only use two way power source.

Default firmware is original 3DR 2.0 version, but we suggest to use MinimOSD-Extra firmware if use on APM.
the MinimOSD-Extra firmware is wrote by Gábor Zoltán.
