iCE40HX8K-EVB OSHW FPGA board is in stock


iCE40HX8K-EVB is upgrade of our iCE40HX1K-EVB with more logic cells FPGA so bigger Verilog projects could be synthesized.

GPIO1 34 pin bus is same as iCE40HX1K-EVB and all DAC, ADC, IO, etc modules are compatible, on top of this there are plenty of additional GPIOs on 4 40 pin 0.05″ step connectors.

512KB fast SRAM is on board, with iCE40-IO board you  can connect VGA monitor and PS2 keyboard, so you can make your own custom CPU (for instance RISC-V) computer with monitor and keyboard.

    I need a Free and Open Source Laptop!… and I would have chosen the Purism Librem line, but the delay in their ability to achieve 100% FOSH, has caused me to search elsewhere! And!… in addition!… their “revamped website” is SO PATHETIC, that their website– ALONE!– is enough to END my further ties to this brand!
    To sum!… those interested in a FOSS+FOSH laptop need an assurance that such will be forthcoming!… WITHOUT THE HOOPLA! And!… FOSH users need a site, wherein the ENTIRE FOSS and FOSH INFRASTRUCTURE is discussed, and shared! And… unfortunately!… the Purism Librem WEBSITE AUTOCRACY doesn’t lend itself to that discussion!
    To sum up… FOSS and FOSH are the way to go!… and those wanting to come on board, need a family that they can trust, and a “gameplan” they can commit to! And that means… and due to the nature of FOSS and FOSH!… A GLOBAL VISION, AND NETWORKING, THAT/ WHICH TIES THE S-E-R-I-O-U-S” FOSS AND FOSH FAMILY MEMBERS TOGETHER! And, its followers need a website that/ which can address any and all aspects of the FOSS and FOSH Global Infrastructure, in order to efficiently and effectively bring the desparate elements of FOSS and FOSH together! And unlike CLOSED SOURCE ventures (what I term Matrixware!), FOSS and FOSH can provide the most powerful integration of ICT ever envisaged on planet earth! But!… and for some strange reason!… many of the FOSS and FOSH players, DON’T SEEM TO GET THAT!
    Please!… no emails!

    Hey Olimex,

    What about making devboard for ICE40UP5K with QFN48 package?

    That would be really nice easy-to-use FPGA board with a lot of RAM (512kBytes) and 8 DSP blocks for computational-heavy applications…

      Yes, it is great to see somebody is now working to support that device inside project icestorm. (see and

      Anycase, my guess is that both the HX8K and UP5K have a market.
      The HX8K board is great (say) to implement a risc-v processor as it has more LUTs. The UP5K is more oriented towards signal-processing with its DSP blocks and PLL.

      There currently only is one single board for the UP5K and that is the very basic board of lattice itself which does not even have SRAM RAM,
      So, in combination with the ADC and DAC addon board for the olimex HX1K and HX8K EVB that already exis, it would surely be a very good addition to have an open-source board with a UP5K too to be able to experiment with high-speed signal-processing.

    Forgive my ignorance, and if this is a silly question, but am I correct in assuming that this is the board I would want if I was wanting to make a *completely* blob free OSHW computer?

    Basically my goal is to create the most trustworthy computer I possibly can in which ALL of the sources and components (both SW and HW) can be fully vetted and trusted (ie. without the usual backdoor / closed-source shenanigans).

    My usecase doesn’t necessarily require a lot of horsepower however the more the better I guess. At its most simple, this machine would be used to generate, store and manage keys and passwords etc. (hence the requirement for no blobs etc.).

    Any help or advice would be most appreciative. I realize I still have a lot to learn.

      Michael, I just ordered one of these boards for this exact same primary purpose. My planned starting point is adaptation of Clifford Wolf’s IcoSoC ( for the Olimex board rather the IcoBoard. I debated getting the IcoBoard but I’ve used and liked Olimex boards in the past and didn’t really like the PI hat aspect of the IcoBoard.

    When will this board be in stock again?
