top | item 45477769 (no title) snitty | 4 months ago The FPGA is a Lattice LFE5U-25F, about $20https://www.digikey.com/en/products/detail/lattice-semicondu... discuss order hn newest crote|4 months ago Or about $5 on LCSC. greenbit|4 months ago Thank you for surfacing that info, was wondering if I seriously had to go start opening files to find out.Btw, that's a 256 pin BGA part, grandad's Weller cannot help. tremon|4 months ago Curious why they didn't use the LFE5U-12F, I can't imagine this project maxing out even the smallest modern FPGA. rowanG077|4 months ago Even better. The LFE5U-12F is just a 25F in terms of resources you can full utilize it with nextpnr. I expect lattice didn't find it economical to have a truly separate production process for it.
