Because Trace II/III/IV use the same firmware, so we change OSD Text as 'Trace IV' in firmware V2.8,
LED status in V2.8:
Power on: LED(blue) blink
GPS locked: LED(red) solid, No blue
What is the difference between II and III?
The Tiny II and III have the same OSD board, the Tiny III just update the GPS to 10Hz, the current sensor of Tiny III is smaller than the one of Tiny II
Trace OSD inludes a PSU unit(Power Supply Unit) in Current sensor module, it can supply 5V/12V power for camera/VTX
Trace OSD inludea the AAT decode unit, it can work with Skylark AAT directly
Tiny OSD is not PSU
If Tiny OSD need connect with AAT conver module before it work with Skylark AAT.
This GPS sensor (using the 4hz) is much more accurate the faster you are moving. It was VERY (or at least seemed more realistic) today while flying the new Radian. My full throttle climbing speed is 45 mph and the altitude caught up very quickly and the speed changes responded much faster.
