it is ,
anyway ,, when connecting bat -> gps/i2c/reciver setting all disable
usb only -> all seems fine.
just strange, seems like a half boot, normal boot , led shoel be blinging like 5 sec then steady , now it is blue 4x slow -> then boot up -> blue -> yello-> blue , etc slowly
edit , this is random ,, got it working ,, but it failes more then it fully boots.
