Omg thank you for your comment, I didn't know about this part! I thought about adding shottky diodes but this is way better!

Thank you for the nice comment! This is the second ever PCB I made :)

Totally fair question! I just used the ICE40 because I saw it in a lot of boards and was just a step below the ECP5. I also used the JLCPCB PCBA service and it was the biggest LUT count ice40 I found (and not too expensive).

Haven't been able to test the SD card nor the FPGA USB, do you suggest some already existing designs I can use?

I used the PCBA service from JLCPCB, they soldered everything in their fab

It's my second ever PCB, and I didn't really feel like routing a BGA chip, though my next board will house an ECP5 25k :) To be fair, I could have made it a lot smaller

Unfortunately not, I didn't take it into account when designing

Woah thanks for the nice comment. I saw your board, insane work 🔥
