Bunnie's Baochip board available through CrowdSupply
This is a really open microcontroller. Kind of like a RaspBerry Pi Nano. Not only is it open (including the circuitry), the software is Rust, all the way down. <https://www.crowdsupply.com/baochip/dabao> Here's a talk he and Sean Cross gave at the 2025 3c (Chaos Computer Conference): <https://fahrplan.events.ccc.de/congress/2025/fahrplan/event/xous-a-pure-rust-rethink-of-the-embedded-operating-system> The video is somewhere, including on YouTube.
Hey you didn't say that this thing is RISC-V, that seems like a big deal too. I like their slogan, "the Most Inspectable Chip" And thanks for introducing me to crowdsupply.com, this site looks interesting... On Mon, Mar 2, 2026 at 12:07 PM D.

I think you meant Raspberry Pi Pico.
You are absolutely right. Thanks. The Baochip's processor has an MMU unlike the Pico's. This gives a glimmer of hope that Linux could run on it but there isn't enough RAM and I don't expect Linux distros for 32-bit RISC V. I have not looked closely.
