For my temp test, I was controlling the fan speed manually since the bring up of the board wasn't done yet. Yes those are 4 pins headers. Beside vcc and gnd, the PWM and Sense pins go each to a dedicated gpio. I haven't yet put the effort on the PWM driver, but yeah it should be pretty straight forward. There are already some generic gpio pwm driver out there.

Yes I took in consideration the casing for the PCB layout ;-) Yup, you right those high performance SoC have some quite high nominal temperature. The casing has a very good air flow transit. In Idle with fans spinning in the low RPM, SoC is around 50C. A bit of active cooling change everything ;-)

@Igor, thanks I will look up for the ongoing change related to the clearfog. That's super great to read that you guys think it's a cool board. I had the strong feeling that I wasn't the only one looking for a board that's finally address the need to build a proper NAS on a fully open source ARM board. Coz yes it's the intention, if the campaign is a success, the whole hardware design will be released as open source (Open Hardware). Haha, well believe it or not, I'm not doing it for the money...If it was really only $$$ that drives this project, I don't think it will actually worth it. My goal is to make it a product that the community likes and adopt...it will be my ultimate satisfaction. But ok deal, if it the campaign succeed, you will get your box of beers ;-) Regarding the price point, I hope people will first understand that this a high performance SoC... it can't come as dirt cheap as some Pi-like boards. And that obviously I won't be manufacturing tens of thousands units. My target is 1000 units. As briefly explained, I will principally offer it as a full kit (AC/DC adapter 12V 8A, casing, complete cabling, fans and a little oled screen). My assumption is that if you set it up a NAS, you don't want a messy setup with HDDs hanging around. You want something neat and clean...and sweet to look at Anyway there will also be the barebone option. The price of the full kit will be in the range of 170 - 200 USD. I'm fully aware of the competition (Synology, WD, etc...) and I can confidently say that apple to apple specs comparison is way cheaper. Here as some pictures of what it looks like with the casing. (note : this is the casing without the oled screen). No. It's non-ECC memory. The SoM supports ECC though, but it will bump the price quite a bit. However it could be a stretch goal or an additional option. I don't wish to open here a discussion on ECC memory in the context of NAS, there are already plenty of years old ongoing threads on [non-]ECC memory for RAID or ZFS. While Helios-4 board is clearly not targeting mission critical application, the likeliness of corrupted data due to bit rot + existing "mitigation" feature (beside doing backups), doesn't in my opinion worth the premium of ECC memory for the scope of this board. Any opinion are much welcome ;-) Cheers. Gauthier.

Hi Igor, Hi Armbian team, I wanted to give a short teaser of an upcoming board I have been developing. The board will be launched through a crowd-funding campaign in couple of weeks. Codename : Helios-4 I'm sure the heatsink will give you some hint The board has been build around the Marvell Armada 388 SoC / SoM from SolidRun. So part of the design is inspired from the Clearfog dev board. Actually the SolidRun helped me on the PCB layout to make this little guy reality. Here the main specs : - dual core A9 @1.6 GHz (max 2Ghz) - 1GB DDR3 (2GB optional) - 4x SATA III - 2x USB 3.0 - 1x Gigabit Ethernet - Micro SD card - Built-in HDD power circuitry for 4 disks - 2x Fan PWM headers - I2C, GPIO and extension pins - Micro USB to Serial - Dimension 100mm x 100mm So clearly I have started this project with one main goal in mind : to finally bring to market the 1st ARM based board which has been designed specially for NAS purpose. I was frustrated to not find any affordable ARM board which has more than 1 SATA port. Optionally the board will come along with a full kit, acrylic casing fitting 4x HDD (3.5'), 2x FAN, oled screen, cabling and power adaptor. Once assembled, it's the smallest 4x 3.5' disk NAS that you could find our there ;-) If people interested, I will post some pic. Anyhow I stop my pitch here ;-) Having used Armbian images and the build framework / toolchain for quite some times, it was logical for this project that the baseline image for Helios4 would be done via the Armbian project. I recently started to dig into your repo to see how to contribute and squeeze my board in. I might need some guidance later, so I hope I can seek a bit of support from the team. I'm also super keen to donate aboard if it can help ;-) Hope it was the right place to post this. Cheers.
