If you read the blogpost on #myStorm that describes the hardware https://folknologylabs.wordpress.com/2016/07/21/a-perfect-st...

It sounds like this board is going to be available for $30 and you add your own Rasp-Pi - but the $5 Pi-Zero plugs straight in on the end of the board.

There's an ARM M3 acting as FPGA programmer, GPIO, ADC and up to 512K bytes of fast SRAM on the flip-side of the board.

For $30 that seems a bargain!
