Yep, and I love it. That's a much smaller (and lower pin count) FPGA than this ECP5, though.

IceSugarPro (with its breakout board) is quite a nice board if you want something pre-assembled. Same FPGA as this new board (so also supported by the Open Source toolchain), same size SDRAM, HDMI out but PMODs for everything else. I really like the look of this new board, though - I definitely want to get my hands on one. (I also have a Tang Nano 20K but don't like it all that much.)

I have the icesugar pro as well. I like the SODIMM form factor because it works well on a cheap four-layer carrier board and it exposes a lot of IO, which is what I want when I'm doing stuff with FPGAs.

This looks like a great project, a fun toy to play with. However, stating that: > I've always wanted a low-cost portable FPGA with video output to make my own CPU, but there isn't any on the market. is definitely not true: one can buy Sipeed's Tang Nano boards for $25+ on Amazon (or less if one needs fewer than 20k LUTs).

Oh that's nice, how come I never saw those!

You stepped up to share something, we shared something back. :-)

Not OP, but these kind of boards are ballpark between $100-$200. Here’s a similar board with the same FPGA: https://www.crowdsupply.com/radiona/ulx3s .

Another similar board (perhaps even more similar than the ULX3S) is the IceSugarPro - it's sub-$100 for the module and breakout board. [I enjoy reading your blog by the way - just last week I picked up a Pano Logic G1 on EBay!]

Thanks! I'm looking forward to your Pano Logic pull requests! :-)
