Another SBC

Hackboard is an Intel based SBC.
During the crowfunding campaign, it is sell at 99$ with Ubuntu installed. Once the campaign is ended, there will be only a window version alvailable (at 140$)
Along with the board itself, you’ll receive a 12 VDC / 3 A international power supply, a heatsink, two board-mountable antennas, an instruction pamphlet, and stickers.

Board has a 40 pins header that is declared to be raspberry pi compatible. And by looking the docs, yes, pins are organized as on the RPI’s.

They are already on the market other boards like that one (LattePanda, AtompicPi, seedstudio Odissey, )… But I think that this is the only one that expose the I2S ports (I may be wrong).

I really ask myself: how much software adjustment will be necessary to get an I2S audio breakout, a zynaptik port expander +midi interface (<=> porting wiringPi to x86_64 architecture maybe ?) to run smoothly on that hardware ???

Find a hackboard forum with people who have tried pi hats?

so long that board is still in the funding stage , I think nobody has ever yet try to do anything with its GPIOs, exept their conceptors (maybe).

I’ve added (maybe) because, I’ve found other Intel based sbc’s:

  • the rockPi X.
    They have inverted the footprint of an IC, see here , and GPIO voltage is 1.8V

  • Up_boards: in the wiki, we can read: " The 40-pin GPIO header has pins connected to I2S for audio. Support is planned, but currently unavailable on official releases." (link to the wiki)

Good point! going to have to wait then. It’s likely onboard audio will be better than pi stock audio anyway.

I’ve asked some questions to the Hackboard team.

At first look, it has really nice features: 12V barrel jack input, two NvMe connectors, a rechargeable battery connector.

Wait and see …

When considering the x86/64 path I would not want to be restricted to platforms with questionable I2S support.
And the CPU on this board is also rather limited with its Celeron N4020, 2 core.
I would rather spend more money and get a NUC or just some standard ITX board with at least an i3 or ryzen 3 just to utilize the power this platform offers and stick to PCIe or USB soundcards instead of I2S.

Sorry for the rant, I just might not be the target audience for this board. :thinking:

Yes, your point if view is absolutely right. Adding more or less problems to get everything working with no or just the strict minimum help from the conceptor, that let you think twice (or more) before buying such a thing.

Sbc’s are pretty cool because of their small Size and their expansion headers. But I had a very bad experience with a rk3399 SBC from friendlyelec/friendlyarm, the NanoPI M4V2, wich died without any warning sign … I’ve just lost something like 100 bucks.

I don’t know if they are some “mainstream” motherboards with I2C and UART headers for wirnig encoders and the MIDI interface

So do I, but I’m pleased to share thoughts about that.

Maybe a RPi Zero in gadget- mode can get the job done?

More for the SBC hype train. This one is RISC-V

Also says it has I2S


Ohhhh yessss!
Sooner than later, zynthian will run in a totally Open Hardware platform, and RISC-V is the way to go. Anyway, we are not in a hurry . Step by step with our eyes and ears very open :wink:

Of course, if some body could build an image for this BeagleV … it would be really great news!!



Good luck convincing modartt they need to do a risc-v build of pianoteq :sweat_smile:


porting drivers of some good audio codec is challenging too !

Wait for a few more iterations though if you want to avoid the x-runs:

The Rpi4B has 4 Cortex-A72 64-bit SoC @ 1.5 GHz with 1MB L2 cache. The A72 claims 4.7 DMIPS/MHz.
This board has a Dual-core U74 (RV64GC) 64-bit SoC @ 1.5 GHz with 2MB L2 cache. The U74 claims 2.5 DMIPS/MHz.

So, roughly 1/4 as fast as a Rpi4B given the roughly half DMIPS/MHz and half the cores.

Don’t come here and ruin everything with facts! We’re dreaming of a pocket zynthian super synth here.

edit: Actually what we’ll need is a neural net based synth to leverage the NVDLA co-processor :smiley:


We are not in a hurry. RBPi is a very good platform and we can live with the fact it’s not open hardware. Of course, as soon as we have an open hardware alternative that can compete on CPU power and software availability/stability, i will be happy to push for the change. Until then, it would be nice to see some brave explorers opening the way, jeje!



An SBC that’s about the same speed as a pi4 so it’s not going to run pianoteq any better.

BUT, it does have emmc storage and the model B could probably be jammed in to an existing zynthian case. Also supports eink displays.

Want to try a RISC sbc: there’s a giveaway of 1000 of them for intrepids developpers:
