Hello Howard,

I do not have an Odroid N2 + , but it does look like a worthwhile upgrade from the N2.

However, be mindful that the brilliance in electronic design is selecting the parts that perform the functionality that YOU require at the level that you require. Whether it be a new Transceiver, or the new latest and greatest PC,? do not be drawn into lots of performance numbers, unless the performance numbers are really in the areas that you require.

Every design is different, there is no design that is perfect. So when you go and buy a PC for Ham Radio it can be a bit of a lottery. It would be fine if you could go into the shop with your Softrock etc and load up your software and see if the USB actually works !!!

I was gutted when I purchased my SamSung Win7 i5 Core Laptop and found that the USB did not work ! It just could not handle two full duplex USB !

The Raspberry Pi with its FOUR USBs ?, well you might get one USB to give you full duplex, but don't ask for two. It's almost like in the old days, when you bought a transformer to operate your door bell, it was stated as a 12 Volt 0.3 Amp unit, the problem was you could not get the 12 Volts and the 0.3 Amps at the same time !

To be honest, there are some rooky designs that have been in place out there for many years now. It would appear the designers / manufacturers have no interest in any rectification of their design deficiencies.

The Odroid N2+ has many shortfalls for sure, as does the original N2, BUT, the question is can it perform to the required standard, all the major functionality that you require for your specific application(s) ?

That is all it needs to do. No more.

On our Scottie Globemaster SDR project we spent many many months on qualification testing with specific Hardware, Software and Firmware before eventually approving the entire package for release to purchasers. The Odroid N2 was one piece of hardware that made the grade and was approved and recommended by us for use with our SDR.? If you change anything, all bets are off !
