HN discussionIts a cool board! Second submission on it ~7 years ago got a tiny bit of traction. https://news.ycombinator.com/item?id=19488397 There's a fun/interesting lesson on some creative routing for the ice40 FPGA FPGA here. Which I re-stumbled into just last week by happenstance. https://danielmangum.com/posts/spi-routing-ice40-fpga/ One of the makers Tim @mithro Ansell is pretty great. A bit quieter on the social media th…

HN discussionAuthor here -- thanks for the feedback! This is a quick post that is focused on how to logically think about the circuit, but I agree that all of the attributes you enumerated are valuable information as well. I plan to continue diving deeper in future posts. I am currently posting every Friday as part of my goal of gaining a deep understanding of chip design[0]. Please feel free to continue to provide feedback on f…
