I'd like to announce the latest open source hardware project "myStorm" - its a fusion of a Lattice ICE40HX4K FPGA with a STM32F103RCT7 playing the support role.
The board will take either a genuine STM32F103 or the somewhat more economical GD32103RCT7, priced locally in Shenzhen at $1.92 in 1 off.
The FPGA and STM32 are connected by and 8 bit bus - with handshake lines.
52 of the FPGA signals are broken out to PMOD connectors.
20 of the GPIO and 6 analogue inputs of the STM32 are broken out to Arduino style shield headers.
It is designed to use Clifford Wolf's Project Ice Storm open source FPGA design and programing tool chain -
You can plug in a Raspberry Pi or Pi Zero directly into the end connector - to host the Ice Storm tools. Both the FPGA and the STM32 can be accessed from the Pi via the 8 bit bidirectional bus.
The boards are now on their way from Shenzhen - and I got a sneak preview this morning from my Shenzhen friend Toby Yu - who is managing the job out there.
It's early days - but these boards were still being worked on in EagleCAD just last Thursday.

Alan Wood and I have created this little 75x75mm board for a forthcoming FPGA course.
It's a no nonsense board for people that want low cost FPGA hardware.
The expected price of this little board is expected to be around US$30
Future versions to work with $9 CHIP, PocketCHIP and recently announced Omega2 - are also at the early planning stage.
Ken Boak, Alan Wood and Toby Yu
