Hi Robin,
As you say in an earlier post on another thread that you bought your Rosetta at Sywell in September 2018, I’m surprised to hear you have been experiencing power and GPS issues this long without resolution. I’m very pleased to hear/see that you have installed one of Jeremy’s excellent Charge2 power units, which should exclude power issues with the supply - unless your aircraft is supplying less than something like 10 volts (I can’t remember the exact figure - I’m sure Jeremy will confirm).
I have to say, the cabling you have adopted looks a bit over the top to me and will certainly be putting a considerable strain on the microUSB socket in the PAW (which I’d say is the most likely cause of your current problems - sorry no pun intended). How far away from the supply is the Rosetta normally located (from the photo it looks like it’s on a workbench or something - not in the plane!). A description or photo of where it’s normally mounted in the plane might help clarify the situation.
While we always stress using the supplied 1 metre JuicEBitz power cable (because of its 20AWG power wires) and limiting to the supplied 1m length, I have in the past successfully run PAW units using 2metre JuicEBitz cables (though can’t guarantee that this will work in every case and if the socket has already been damaged that won’t relieve the issue).
If, as I suspect, the socket
has been damaged, it ‘can’ be ‘re-tightened’ slightly - or replaced, but this is not a job for the amateur solderer - and is usually more economic to replace the Raspberry Pi Motherboard.
Alternatively, if you also suspect that there are other internal issues it might be best to arrange to return the unit to PilotAware for testing / repair. Contact Ash via
