A more modern Marvell SBC
Bought a used board. It came with a nice box, bare board, 8GB micro sd card, power supply, and micro usb cable.
Took a bit to figure out there were different revisions, and the official cases don't fit because they combined two RJ-45s into a single module.
It boots ubuntu xenial, but with a seemingly unpackaged kernel/uboot.
Building
Got this thingiverse snap case by plushvoxel made up. I collected some other bits to make it go together.
- stick-on pcb based wifi antennas
- M.2 2242/2230 to SATA PCB with 3.3V regulator (ebay)
- BiWin 128GB SSD I pulled from GPD MicroPC
- 5" thin SATA cables
- Intel 7260-HMW mini-pcie card w/ full-length extender
I had to make up a molex sata power cable. Case was too short to allow a normal molex to fit. I probably could have cut it down and made it work, but I found a IDC style molex instead that was much lower profile.
The marvell chip needs some heatsinking. I stuck a copper one on and it still get quite hot. Remains to be seen how it will hold up under a load.
