  • FPGA development board

    For quite some time now, I wanted to experiment with FPGAs. As it is, there’s lack of time, energy and motivation. And, also for me, the urge to “find the perfect solution”, in this case, the perfect development board.

    As COVID hit me for this years’ Christmas, I had a lot of time. And also boredom. By chance I stumbled upon the Tang Nano 9K development board. It’s surprisingly cheap, and it could even run a picoRISC-V, something I wanted to play around with as well.

    Alas. When looking at where to get it, the only solution was to get it from AliExpress / China. It’s not available at any European distributors, apparently. (For ecological reasons, I don’t want to order there anymore. I don’t want to participate in this Temu, and whatever these the other shops are called, hype.)

    So I already put the project off the table, When suddenly EBay notified me a German individual put one for sale. Yes, you may criticize me for that, since the board still comes from China, but I find in more bearable for myself to buy used stuff.

    So anyway, here it is:

    Photo of an PCB. It is a Sipeed Tang Nano 9K, an FPGA development board.

    I already started playing around with it, you can follow my learning progress on my Git repository.

    I have next to no knowledge of this topic altogether, so it’s something entirely new for me! Exciting!
