The pins aren't labeled on | the board, and they're in a weird layout, with some male and | others female. | the__alchemist wrote: | How does this compare to alternatives for learning FPGA?

Crazy good board for the price. | No OSS tool chain though. | noncoml wrote: | I had fun playing with the Lattice ICE40 Ultra Plus Breakout | board. | | I wouldn't call it expensive (~$60) and it's pretty simple. | | The toolchain by Lattice however is not the best | funkaster wrote: | I was looking for a cheap (< $30) board to start playing with | FPGAs and found this one.
