This would be better if there was a link to the actual product.
They have an intro to the myStorm board at https://folknologylabs.wordpress.com/2016/07/21/a-perfect-st... : "myStorm is the perfect combination of a $5 Raspberry Pi Zero, a $1, 32-bit ARM microcontroller and a $5 versatile low power FPGA – an open hardware platform – brought to life with innovative open source software."
I love all the FPGA boards coming out but I really wish the software was better. Lattice uses the same synthesizer as Xilinx which is well known to be completely user hostile (will silently optimize huge swaths of code because it doesn't like them). The least headaches come from Altera but that's not a high bar...

This chip from Lattice is supported by icestorm. It is the only open source FPGA tool chain. http://www.clifford.at/icestorm/
I'm at my hackerspace right now. There's three people with HX8K evaluation boards at this table alone (I've got two, actually). None of us have even downloaded the Lattice tools.
I've got the HX8K eval board doing text over VGA at 1280x1024 with a simple home-etched PCB that plus into it and some very naive code, hope to hit 1920x1080... It's a lot of fun. The toolchain has some niggles, but overall it's extremely pleasant and I'm so happy it exists. I've been wanting to work with programmable logic for a few years since getting into electronics, but I've just not got along with the Xilinx and Altera tools.

In response to Joshu - I don't think this is a Kickstarter Campaign - I get it's two guys in the UK doing this off their own backs - and in record time - design on laptop to working board prototype in less than 2 weeks - with the pcbs made in Shenzhen China, in under a week. There on Twitter under #myStorm - if you want to check them out
> - and in record time - design on laptop to working board prototype in less than 2 weeks Well, it looks like there are 3 chips, a usual DC-DC converter, and that's all :-)
It looks like they have 512K bytes of 10nS SRAM on the back of the board - but it's neat how the $5 Rapberry Pi-Zero plugs in at one end - some cool overall pics on Twitter if you search #myStorm

Unfortunately IceStorm has only reverse engineered the 1K and 8K, not the 4K.

And I think you'll find this is the exact reason the iCE40s are showing up in so many hobbyist projects. I'm at my hackerspace right now.

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!

Really? On the http://www.clifford.at/icestorm/ IceStorm site - If you look carefully at the table of supported devices - the ICE40HX4K-144 is there - 2 rows from the bottom

Am I right in thinking 8K refers to the number of LUTs/cells? If so I won't be fitting the Rocket RISC-V design in one any time soon. Although it's a good start - I'll be very happy to see the back of Xilinx Vivado awfulness one day.

In what way would it be better? Two guys doing something cool - what do you want? It's all opens source - you go make one in 10 days!
