I very much respect Espressif products, specially because how good their documentation is. I wish though somebody would package an ESP board with 256 Mb of RAM or more... From what I've seen, that amount of RAM seems to be exclusive Linux SBC territory, but Linux doesn't make sense for a lot of projects.

Sadly this S31 can address up to 64 MiB of PSRAM at most. And only 32 MiB SKU has been released.
