Hi All,
Just building my first PilotAware and as I had a R280T2 I thought I would try it, it works with no changes
software reports it as a R820T so in case I was sold a dud I opened it up and the chip is labeled R820T2.
It is said to have less drift and better reception then the R820T.
I'm not completing the build until I have the board from @JCurtis and the USB GPS, can't wait!
