Interestingly....,
I went flying yesterday. I was running 2 x mini iPads and an Aircrew Display from my PilotAware Rosetta (with an 'experimental' Pi3B+ motherboard - which has been in extensive use and in and out of the plane since May 2018), together with an 'independent' FlarmMouse and LED Display installation - as I was flying in to check an OGN-R rebroadcast station at an busy active gliding site.
All was well on the outboard leg and as I approached the field, I could see lots of active gliders on my SkyDemon display - and on my 'Aircrew' from about 10 miles out. As I got closer, the gliders also started to trigger 'warnings' on my FLARM system from about 2-3 miles away.
After a short visit, I headed back to my Home field with all initially well, then shortly after climbout, I started to experience dropouts on SkyDemon - which kept displaying the
'Waiting for Device' warning - indicating that no data was being received from my PilotAware. The sound of the audio announcement
'PilotAware' through my headphones, advised me that the unit had rebooted and a quick check of my PAW Home Screen confirmed a Voltage Error with Throttling of the Processor - i.e. a Power Fault. As I was heading back to my home airfield, I decided to continue, with the unit showing my track between several short breaks / restarts, indicating the probability of a cable / connector fault.
I have since carried out some tests with the unit connected to a monitor via HDMI (initially by wiggling the cable), which immediately shows up an 'Under-voltage detection' and if repeated or continued causes the unit to shut down. Trying a spare (brand-new) cable reduces the incidence of the fault, but not entirely, so I guess it's time to bite the bullet and order a new Motherboard -
I just posted this to show that it can happen to the best of us (and me), so be gentle with the on-board micro-USB connector - or preferably leave it alone and do all your connecting/disconnecting at the larger (USB-A) end of the cable!
