The iCEBreaker FPGA campaign is now live

The idea for the iCEBreaker FPGA development board was originally written down as a design requirement document by Clifford Wolf of Yosys/icestorm open source FPGA development tool fame. After discussing the project with Clifford at the Chaos Communication Congress in December 2017, Piotr Esden-Tempski of 1BitSquared took on the project in January 2018. Since the first draft of the design created by Piotr at Clifford’s apartment in Vienna, the iCEBreaker has had five hardware revisions, a workshop at Hackaday Supercon, and hundreds of hours of testing and development by enthusiastic users, developers, and educators who we were able to bring onto the project early on.

Now, we are proud to launch the iCEBreaker Crowd Supply campaign to finally make the hardware available to everyone. We hope you will check out the main project page, back the campaign, and help make iCEBreaker a reality!

Product Choices



Your own iCEBreaker FPGA development board and headers. Learn how to design digital logic, experiment with your own CPU core design, and build your next innovative project.


iCEBreaker DIP Switch Pmod

Single Pmod is ideal for simple exercises as well as an 8 bit input for your FPGA project. Required for the WTFpga workshop.


iCEBreaker 7-Segment Pmod

Single Pmod is ideal for simple exercises as well as number indicators for your FPGA project. One is required for WTFpga workshop and you will need two for the iCEBreaker workshop.


iCEBreaker 12-Bit DVI Pmod

Dual Pmod is ideal to add digital video output to your FPGA project. It is as easy to use as an analog VGA output without the need for high speed differential signals and encoding.


iCEBreaker LED Panel Driver Pmod

Dual Pmod to interface your FPGA project with a HUB75E interface RGB LED Matrix. By default configured for 3.3V signaling but can be switched to 5V signal shifting for those LED Panels that need it.


RGB LED Panel P2 64x64 (ICN2037 Shift Registers)

A tested and documented RGB LED Matrix with easy to use ICN2037 shift registers.
