ASUS 17 Inch Touch Screen
#1
Does anyone have any experience with this unit? It seems like a good deal. I wouldn't use it in the cockpit, but it looks good for the nav station.

Oops, changed my mind! This popped up in some searches. It looks like the small, 12V powered RPI screen that I've been looking for a long time.

I went for the Asus mb169b+ 15.6" full hd 1920x1080 usb 3.0 portable monitor (takes power from a small factor Intel NUC PC which works on 12V).

But no touch on this model.

Hi Jeroen,

Good Suggestion, I assume you are running MS Windows so no openplotter ?
Intel NUC, runs on 19 V isn't it ? What power supply are you using ?

I do run OpenPlotter on a Raspberry 3B model while the Intel NUC provides more then needed CPU/memory for OpenCPN.
The Intel NUC runs on 12V, I simply wired it to the 12V circuit. There is a small inconvenience however.

When docked in the marina and the battery charger activated, the NUC detects a voltage which is to high (>14v) and refuses to boot. I simply turn off the battery charger for 5 seconds and let my fridge/lamps/electronics draw some power from the battery, then the NUC boots fine and is perfectly stable (for days), even with battery charger back on.
The same issue reproduces itself when under way at sea on engine power. I simply power on a lot of lamps just to get a large draw on the batteries to get past the Intel NUC error prior to booting. This is not really an issue because the Intel NUC runs stable for days and nights. I prefer a device mounted high and dry over a laptop which can fall and break, especially because I use it for radar as well.

I do plan to test with the USB 3.0 monitor straight on my Raspberry so that I can eliminate the Intel NUC.
Possibly the USB 3.0 monitor + Raspberry won't work without an optional USB 3.0 Y cable + powered USB 3.0 HUB (don't mind the Raspberry 3B only supports USB 2.0 high speed, this is not an issue, it should work).

My hope is to get the monitor working withouth the optional cables. According to the official Raspberry site 1.2A (6W) is the max. total power draw for USB peripherals. The monitor uses 5W according to some sources, "<7W" according to other sources.

The driver issue from the past has been sorted out as well, it works on Linux Ubuntu/Mint/Fedora and also on Raspbian (providing sufficient power is available).

As soon as I have a good result, I'll post my findings here.

Update: latest generation USB 3.0 monitors will not work on Raspberry since the displaylink drivers for linux are for the x86 Platform, not ARM.

For those interested to have their 13~16 inch USB-powered monitor (eg. ASUS) working on Raspberry/OpenPlotter, you can vote here:

Today, these only work on Windows x86/x64 and Linux x86/x64, not ARM.
It takes quite some energy to both have a Windows x86/x64 with OpenCPN and Raspberry/OpenPlotter powered on when underway.

I've never tried a Displaylink monitor, but according to this thread, Raspiban supports it. Is it just the Asus monitors, or am I missing something? I really want to know, because I've been searching high and low for a decent 10'+ touch monitor. I always thought that the Raspberry Pi foundation missed a bet when they didn't release a native 10 inch monitor.

There are many manufacturers and models with Displaylink technology. Only few of them offer USB 3.0 powered screens, Asus and AOC first come to my mind but there are other unknown brands.
What I learnt:
- even if your device supports up to USB 2.0, these USB 3.0 devices are usable, maybe less for movies
- ARM v8 (=Raspberry) is not supported, the Linux drivers available are for x86 platform, in theory you can now download Raspbian Desktop x86 and it should work, but you would have used an Intel/AMD device, not a Raspberry
- If ARM support gets figured out, power could be an issue, the larger the screen, the higher the need, for the 15.6 inch ASUS, it should be around 7W, and that is slightly above what a Raspberry can deliver, but I guess that can be tweaked by lowering brightness

That's why I shared the link, if Displaylink can be persuaded to invest time in ARM support as they did earlier for Linux x86 and for Android, we could own a very low power Navstation with desktop like capabilities.

Another type of display which might interest some of you: e-inkt, sun readable but no color (or only 3 colors on some sizes) and not a touch screen sensors) at following site https://www.waveshare.com

e.g. 9.7" https://www.waveshare.com/9.7inch-e-paper-hat.htm

That looks great. I guess my major issue with all these sorts of things is packaging. This is definitely something I would want to put on deck (also, their much less expensive three color 7 inch model looks really good), but creating a good looking and waterproof cover or frame is the challenge.

Something 3d printed, perhaps? I just don't know.
