This board is basically just a Lattice iCE40 FPGA, a few support components, and a bunch of pin headers, some of which are in the not-so-handy Arduino pinout footprint. By porting some Acorn Atom ...

An FPGA development board with far too few output pins ... (Hackaday.io has two Arduino clones using SVG pinouts: in SMT and DIP formats.) The iCE40 FPGA has 144 pins, so you’re probably ...
