Any modern replacement for HC2 ?

Post by reukiodo »

Is there any modern replacement for HC2 ? I am not interested in the HC4 as it takes 2 3.5" drives and is nowhere near as compact as the HC2. I am only interested in an SBC which powers a single 3.5" drive.

Ideally an improvement would be USB C (12V) power instead of a barrel plug. And even better to support PoE on the ethernet for a single cable solution.

And bigger bonus if it just slaps on the back of the 3.5" drive with the other ports sticking out the backside of the PCB. Similar to a lot of IDE/PATA to SATA adapter boards, such as https://www.walmart.com/ip/623526151 for example.

Something like from a top down view:

Code: Select all

|            3.5" drive                          |
|________________________________________________|

    !----------!!-----! SATA
================================================== <- PCB
 |_|                           |  | |  |  |      |
                               |__| |__|  |      |
USB C                                     | eth  |
                               USB A      |______|
power/data/video?
or back view:

Code: Select all

__________________________________________________
|                                         _______|
|                              ____ ____  |  --  |
| _                            |H | |H |  |--  --|
|| |                           |H | |H |  |      |
||_|                           |H_| |H_|  |______|
|________________________________________________|
Sorry, please forgive the crude ASCII art.

Obviously placement of the ports on the back can be moved anywhere to make the SoC and other components fit the compact layout.

Well, the short answer is no - there is no current model of Odroid that ticks all your boxes. But you could adapt existing models and see if they get close to your needs:

- HC4 - check out hominoid's Cloudshell4 Unauthorized designs for an alternate case: viewtopic.php?t=40769
- M1 - needs a hardware mod to enable 3.5" HDDs: viewtopic.php?t=44291, plus you'll need a case: https://github.com/hominoids/SBC_Case_Builder (check the m1_fitted_drivebox* variant, or ghe pizzabox one)
- M1S + usb-sata adapter. Note that for 3.5" drives you need 12V, so it will be more complicated (2 PSUs may be needed)

See what's beat/easiest to implement for you!

That's another fun idea for M1S add-on - with PoE, 12V -> 5V Buck converter, and two terribly slow SATA ports - one connected to eMMC interface, and another through USB2. :D
I would just stick to HC2...

Not a bad idea. It could support usb3 to sata via a cable from the usb3 port, even if it's ugly. Maybe have a jumper to allow the user to select if the user wants the usb2 port via the board-to-board connection, or via usb3 external (assuming such a usb switch can be implemented easily.

Ideally I'd like to avoid all the extra cabling of these solutions.

- CloudShell4 is huge, much much larger than a single 3.5" drive
- power mod on M1 is interesting, still quite large, but maybe similar in size to the top of a 3.5" drive
- M1S is not really much different than any other SBC in regards to connecting a 3.5" drive, needs USB->SATA and even though USB C supports 12V, M1S seems not to, requiring a separate 12V power

These features are what made HC2 so unique.
