(Part 2) Best products from r/ODroid

I dunno, 2.5x0.8mm is pretty easy to find on amazon. The same goes for the 5.5x2.1mm, that one is probably the easiest as a number of them are made with plugs that work in 5.5x2.2mm as well.

When you want to load a new OS on your eMMC there's a two-part adapter to get from the USB-A port on your computer to the eMMC chip.

• The $9.90 item is definitely the first piece, a USB-A MicroSD card reader, I can't tell if it includes the second piece also..
  
  
• The $1.50 item is just the second piece, the MicroSD to eMMC adapter, because many people already have a MicroSD card reader.
  
  I already had this card reader and it works perfectly with the $1.50 MicroSD to eMMC adapter. Ameridroid lists them both separately and together, and when together it says "eMMC to microSD Adapter + Transcend USB3.0 reader/writer [0091 0106-NE]"

If anyone is interested, I got this adapter from Amazon, and it works on the C2 with Android.

I had to modify my buiid.prop, and ad the line "wlan.modename=rt2800usb". I added the line under #Additional Build Properties section, right above the wifi.interface line. Rebooted, turned on wifi under settings, and it works.

Not the fastest wifi on the planet, and it seems to take a few attempts to connect to the play store for it to "settle down", sort-of. Seems to be working fine, though.

EDIT: These are RT5370 based dongles.

Really if you get the 40x38x36 heat sink and put a good low RPM 5V fan on it the thing will easily be able to run with minimal thermal related downclocking while still being silent. It's much more effective to add even a small amount of active airflow than to use progressively larger heatsinks.

I did some research and ordered this from Amazon. It works perfectly on my C2 running CoreElec (latest stable). YMMV.

I've done the installation twice using those steps and haven't run into a problem yet. The only thing I didn't do was the very last sync command since the archlinuxarm website didn't list that. (I'm super noob so I just follow the instructions to the letter.)

I'm hoping you just have an sdcard type/brand that the odroid just doesn't like as opposed to having a bum board. But you stated that you replaced the sdcard already. This is the sdcard I'm using.

I recently got mine as well so I don't know if not having an sdcard gives any sort of post messages but I guess that's something you can try.

Ah okay, thanks

So is really any push-button compatible for an external power button? For example this one https://www.amazon.com/dp/B017KP67GI/ref=cm_sw_r_cp_ep_dp_TBY.BbXEG0FKM

802.3af is 15.4 watts, 802.3at is 25 watts, 802.3bt is 100 watts. From my understanding these are the amount of power output at the Power Sending device. This doesn't account for the 15%-25% loss while going over the fairly thin Ethernet cables. I use LINK for my HDHomeRuns, rPis, Microtik Switches, and Rokus. They work pretty well. They're all powered from a Cisco 3560.

Well, I'm going to be using a Noctua fan (Noctua A-Series Cooling Fan Blades with AAO Frame, SSO2 Bearing (NF-A4x10 FLX) https://www.amazon.com/dp/B009NQLT0M/ref=cm_sw_r_cp_apa_i_75GcBbXV86GKS). Do I need to worry about that with this?

I see, very helpful.

Is voltage drop a concern with many odroids on one powerstrip eg This power strip is rated at 15A, if 10 xu4 need a minimum of 40A would that strip power all 10?

I purchased a new UHS-1 class microSD. Specifically a 64 GB PNY XC: http://amzn.com/B00N2ROG9O

I have made sure the switch is positioned correctly on the device. When I follow the steps to install Arch on the microSD, the unit never boots. The red LED stays on for hours until I turn it off.

looks like the sata connectors don't fit well with the acrylic case, you may want to use angled connectors such as this one

I can easily answer your first question. If you install an eMMC module you can use the microSD slot as extra storage. Boot defaults to the eMMC. iirc, it's not a spring loaded microSD slot so not the easiest to work with. If you're planning on moving it around a lot just grab a cheap usb microSD reader.

I don't use mine for anything multimedia related, at least so far, so I can't really answer any of your other questions though. I run Armbian on mine.

A RPi Zero (not W) is $5, if you can get it locally, and a USB Ethernet adapter is as cheap as $7. So, $12 vs. $60+S&H

Just putting into perspective that a PiHole would be even more of a "waste" of an XU4 (using OP's phrasing), unless the XU4 is running multiple services (e.g., PiHole in addition to NAS).

So then you'll have to get an AVR programmer, or buy their FTDI cable.

http://www.amazon.com/dp/B00LK95VNQ might work, or a similar HDMI to Composite converter.

There was a used APC model (like the one I bought) on Amazon for $34.99.

It may be overkill for your application, but you can never have too much overkill...
