got myself an ODroid-HC1, but seems I forgot some things...
Power supply!
I have a right sized barrel to USB cable, but my Ankar is rated up to 3A and is fused at any draw above that. I remember looking at power supplies before, but can't find the link.
UART to USB.
The ones I have won't fit. They are for connecting to pins, not a connector like the HC1 has. What do I get? Plus what are the pin-outs? I really need to get a schematic for this...
Case cover.
For some strange reason, I thought it would come with a cover. I see now, that if you stack them you only need one cover, so it is most likely a separate order. The unit came with a small bag with 2 screws, but I cannot find any holes in the case for any screws! Strange.
So after I get at least the power supply and UART to USB for console, I will be asking how to get this to boot completely from the HD like I do with my Cubies!
thanks
Bob
OK, I found the AmeriDroid site. I overpaid from ebay...
I see the case cover and power supply, but their uart-USB is very pricey. I am use to paying ~$2 each for the ones I get for my Cubies.
But further research shows they use a different voltage so perhaps stuck with the higher price. :(

The Odroid UART to USB cable detects the right voltage (3.3V (AMLogic, RockChip) vs. 1.7V (Samsung)) to take, so you don't have to worry about it. The connector itself allows to be used with single breadboard cables (pin diameter & pin distance), but I haven't found any cheap UART to USB adapters running at 1.7V.

Your statement is a little unclear to me. Are you saying that I CAN use a regular 3.3v adapter, as it detects it and works properly. Or are you saying, it detects the 3.3v and just does not work; that you have to use a 1.7v adapter?
thanks
I have done a bunch of googling and have a better understanding of Odroid's choice of 1.8V UART and the basic unavailability of units at this voltage. Just looking for a CP2104 does not cut it, as they still manage to use 3.3V...
So I will just order the one from AmerOdroid. If I get another board, I will see about just getting the cable so I can move the converter between boards if needed.
Thanks

I wanted to say that Samsung SoCs (as in the HC1) use a 1.7 ttl voltage level in contrast to the very common 3.3v. You will damage the HC1 when you connect a 3.3v adapter to the UART connector. The Odroid UART-USB adapter is able to switch between both voltage levels automatically, so you can use it with any Odroid board.
The Odroid C1 and C2 (and the N1) are using 3.3v levels. For these devices you can use a regular 3.3v adapter and connect it with breadboard cables with the UART pins on the board.
