I started with and still use occasionally a RPi 3B with the stellarmate OS. Later I bought a NanoPC-T4 which has 4 G ram USB 3.0 and an M.2 slot to which I have a 240G nvme drive connected. It runs on 12v 2a which as has been mentioned in the thread is very convenient, no buck converter or big battery needed. I run the complete system from two small talentcell batteries.
Recently I bought an A5X Max Tv box ($47) flashed it with Armbian ubuntu 18.04 and it works fine, has 4G ram and USB 3.0. It does however require 5v 2.5 amps so I need to use a converter.

I use a Rock64 configured to boot from a 240GB SSD, currently with Ubuntu 18.04. I run all the indi drivers for my devices (CEM60 mount, QHY cameras, Rigel focuser) on the Rock64 and I run Kstars/EKOS on various x86-64 systems in my house (or travel trailer when I'm at a dark site). My Rock64 has 4GB RAM, USB3, USB2 and requires 5V,3A power (but rarely exceeds 2amp draw).

The only issues I've encountered are with USB3 hubs, and I haven't found a good one that is robust and can survive operating outside in an observatory. Even though they are shielded from weather, the reliability is low and performance is sometimes an issue. I'd be interested if any of you can recommend a robust high-quality USB3 hub.

jmh, how do you power the Rock64 when at a dark site? Do you have a custom 12 V to 5 V converter that produces the required 3 A or does the Rock64 boot with standard cigarette plug converters? The reason I ask is that the Odroid XU4 refuses to boot at less than 3 A.

I have had good luck with this 12V hub over the past year, it came through the winter outside in obs okay.

No eBay APP ID and/or Cert ID defined in Kunena configurationI am using a 7 port USB3 12 volt powered HUB. It is mounted inside a case with 3 of the ports accessible on the outside. It has never given any trouble and works perfectly with linux systems. (Odroid XU4). Used outside in heavy dew many times.

I am running Ekos on this miniPC, which has USB 3:

I am accessing Ekos / the miniPC via realVNC from the tablet.

Mac mini for Kstars at home and Odroid C1 for the indi server part as remote.

Hi all, i have two devices.

My main device is an Asus Tinker Board (www.asus.com/au/Single-Board-Computer/Tinker-Board/).

My my back up is an Intel Compute Stick (www.intel.com.au/content/www/au/en/produ...tick/stk1aw32sc.html), only because the USB and Wifi is less reliable than the Tinker Board.

Both devices are setup in hot spot mode (I'm a mobile imager).

Cameras and GPS connect via a 12VDC powered USB3 hub and the mount via Wifi.

I VNC with my tablet/laptop.

Hey!

Are you using the Rock64 or the Rock64Pro? It looks like a good alternative.

Greetings,

Thanks
