MyStorm - BlackIce II
BlackIce II is an OpenSource Hardware FPGA development board sporting a massive 56 PIOs and 26 GPIOs with both PMOD expansion sockets and support for Arduino shields. It has an onboard Arm Cortex M4 microcontroller and a 144 pin Ice40 FPGA with 3520 logic cells, 80Kb internal block RAM and 2Mb external SRAM.

Why we made BlackIce..
As makers we fell in love with IceStorm opensource Verilog toolchain back in 2015 and wanted to create a best of class independent opensource hardware development board to fully use the IceStorm FPGA toolkit. You can read some of the background of Mystorm debut at OSHCAMP 2016 ( BlackIce is a leader in it's class for opensource FPGA hardware, it's IO capabilities exceed other ICE40 dev boards. It has been refined through 3 generations and has been proven in applications and deployment spanning over 2 years, it's got some real pedigree!

What makes BlackIce special..
BlackIce II provides maximum PMODs (peripheral modules) for building hardware add-ons and applications, way more than the competing Ice40 development kits. It is also completely OpenSource hardware making it easy for others to build on top of it's design, especially when combined with the OpenSource IceStorm Verilog toolchain. Unlike some other microcontroller only development boards BlackIce II allows opensource hardware to be actually designed and synthesised using Verilog in addition to programming the onboard STM32L433 microcontroller with an Arduino compatable IDE, This combination is very powerful for tackling challenging maker projects like robotics, Retro Games, RISC V designs, SOCs, IOT, motor control and embedded applications. Further it can be connected too and programmed entirely from a Raspberry Pi computer to create even more powerful standalone embedded linux solutions.
