Which Raspberry would you recommend?

I'm going to try VH on a Raspberry to remote control my telescope. There are a few USB devices, only one of which actually uses any serious bandwidth, but I also want to put a gigabit ethernet adapter in there to get extra speed vs the 10/100 built in ethernet. Using a USB3 to ethernet converter people are reporting around 300 mbps.

Anyway, the devices are

Auto focuser - Just serial commands for position and returning temperature once per second (9600 baud)
Scope control - another 9600 baud serial connection
Canon DSLR - commands but also a download of rather big RAW and JPG photos every few minutes. Its USB2 and I think it uses every bit of bandwidth it can.
As mentioned, the gigabit adapter.

Since the Raspberry is doing nothing other than transferring bits from USB to the ethernet adapter I'm thinking it probably doesn't need super-speed and a Raspberry 2 should suffice?

I know there's no big price advantage but everything will be run off an inverter and battery so the lower power consumption of the 2 is attractive.

What do you think? If the 2 will struggle then I'll go with a 3.

Actually ive been quite impressed with the NanoPi NEO2 because its cheap, has gigabit and very small. http://www.friendlyarm.com/index.php?route=product/product&product_id=180 Its much faster than the pi and runs a mainline kernel. You can download an image from here https://www.armbian.com/nanopi-neo-2/ then run the arm64 bit version of virtualhere on it.

Holy cow, what a great little

Holy cow, what a great little unit! In fact, I just ordered the complete kit with aluminium case and OLED etc. Only 1 USB port when I need 3 but that's what hubs are for. Thanks for the tip!

Might have to order a couple more later for other projects.

I forgot to mention you should get the heatsink for it, its an extra US2.97

Comes with the complete kit I

Comes with the complete kit I believe. If not, I have a few small ones kicking around someplace.

Just received my Neo2 this

Just received my Neo2 this morning and spent an entire 5 minutes putting it together and getting it running.

Next question - which server version? Same as the Pi3? Can't find any details about the Neo2 other than its A53.

Great, no it runs the arm64 version of virtualhere, whereas the pi3 is 32-bit.

So do this

wget https://www.virtualhere.com/sites/default/files/usbserver/vhusbdarm64
chmod +x ./vhusbdarm64
sudo ./vhusbdarm64 -b
