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 ???
