Good if you're expecting an Xtensa chip
These little boards are helpful! However, this revision uses an Xtensa LX6 - which is a pain to get working compared to the RISC-V revisions.That's especially true for Rust users - RISC-V is fully supported after you run the single `rustup` installation command. However, Xtensa boards require an extensive setup, which is unsuitable for beginners. Afterward, you'll likely face weird, undocumented problems that leave you running scripts for hours.If you do end up with this version, there are limited online resources to assist you. The setup documentation isn't detailed, and some pages are contradictory...As such, I don't recommend this version of the board. Grab some fancy RISC-V revision - you won't regret it!
