Oxidize XIAO — An Embedded Rust Community Program
A community giveaway program by The Embedded Rustacean × Seeed Studio to grow the embedded Rust ecosystem
The Status Quo 🚧
Embedded Rust is powerful, but getting started can be tough. Navigating the Rust language and embedded ecosystem can be challenging enough; add to that the traditional challenges of embedded development. Special tooling (cross-compiling, logging, debugging, etc.), overwhelming hardware choices, and limited learning resources compared to other embedded ecosystems. That's a barrier to adoption, and it's limiting Rust's potential in embedded.
We believe two things will drive embedded Rust forward:
Making it easier to start. More content, better tooling, and a consistent hardware reference that learners can rely on. No more guessing which board to buy, spending significant time wiring or setting up tools and projects.
Getting adopters to contribute back. Every driver written, every tutorial published, every tool built by the community compounds. Growth fuels more growth. What makes Rust unique among languages used in embedded systems is its passionate open-source community. The question should not only be whether one should learn embedded Rust, but also where or how they can contribute to improving it.
Introducing Oxidize XIAO 🌱🦀
To tackle this, we're launching Oxidize XIAO. Oxidize XIAO is a community rewards program by The Embedded Rustacean (TER), Seeed Studio, & JetBrains.
The name says it all. We want to oxidize XIAO with Rust.
At the heart of Oxidize XIAO sit two platforms: µFerris, an open-source learning board designed specifically for embedded Rust education, and the Seeed Studio XIAO, a family of compact, powerful microcontroller modules. Together, they offer an affordable, well-documented foundation for learning and building.
Here's what the program offers:
Free hardware, tools, and books — given away every month to active community members
A quarterly build challenge — rewarding those who create and share real embedded Rust projects
A path to ecosystem integration — outstanding projects can be invited into the µFerris-rs GitHub organization
The goal is not just to give things away. We aim to create a cycle where learning leads to building, building leads to contribution, and contribution fuels more learning for everyone.
How It Works 🔍
Oxidize XIAO runs on two tracks: a Monthly Subscriber Giveaway offering a prize valued at more than $350 and a Quarterly Build Challenge offering a prize valued at more than $450. Read on for more details about the tracks.
Monthly Subscriber Giveaway 🎁
Every month, we will draw one TER newsletter subscriber to win an embedded Rust starter pack.
To enter, you need to:
Be an active subscriber to The Embedded Rustacean newsletter
Refer two new subscribers
Answer the monthly discovery question (included in each newsletter edition)
The prize pack (> $350 in value):
A µFerris Baseboard ($25 Value)
A Seeed Studio XIAO module (Up to $15 in Value)
A JetBrains All Products Pack 1-year License — includes CLion for embedded Rust development ($299 Value)
A Free eBook copy of Simplified Embedded Rust (edition of your choice) ($30 Value)
The first draw will be at the end of July 2026. Winners are announced in the newsletter and on social media channels.
Quarterly Challenge — Build with XIAO and Rust 🏗️
Once per quarter, we run a build challenge. Create a project using any Seeed Studio XIAO board with Rust and share it publicly.
Any project using a XIAO board with Rust qualifies. You don't need to use a µFerris board to participate. All submissions that meet the eligibility criteria are entered into a random draw. We review submissions to ensure they meet a minimum quality bar — the project must be functional, use a XIAO board with Rust, and be publicly accessible. All qualifying entries have an equal chance of winning.
How to enter:
Build a project or create content using any Seeed Studio XIAO and Rust
Publish your project/content on the XIAO Project Hub
Share it on social media (LinkedIn, BlueSky, or Twitter) tag @theembeddedrustacean, @seeedstudio, and use #OxidizeXIAO
Submit your entry via the TER submission form
The Prize Pack (> $450 in value):
µFerris Full Kit (Baseboard + Power Extension Board) ($40 in Value)
A Seeed Studio XIAO module (Up to $15 in Value)
The Embedded Rustacean Branded T-Shirt + Sticker Pack ($40 Value)
A JetBrains All Products Pack 1-year License — includes CLion for embedded Rust development ($299 Value)
Free ebook copy of both editions of Simplified Embedded Rust ($60 Value)
The first challenge cycle will be for Q3 2026. Winners are announced in the newsletter and on social media.
Recognition: Outstanding projects may be invited to join the µFerris-rs GitHub organization, becoming part of the official ecosystem.
Project & Content Ideas 💡
Not sure what to build? Here are some ideas to get you started
Tools 🛠️
- A
xiao-generateCLI — A project generator for XIAO boards mimickingesp-generate. Pick your board and project configurations to get a ready-to-build project.
Board Support 📦
Extend the µFerris BSP — Help maintain and expand uferris-bsp to support all XIAO variants.
Add Sense support — Integrate the XIAO Sense modules (camera, microphone, IMUs, etc.) into the BSP or as a standalone BSP crate.
Write HAL drivers — Port XIAO peripheral drivers that don't yet exist or are unmaintained in the Rust ecosystem.
Educational & Community 📚🏡
Blog series — Write tutorials that experiment with and highlight community crates using XIAO and/or µFerris as the reference platform.
Video walkthroughs — Record and publish guided builds or exercise walkthroughs.
Interactive tutorials — Create step-by-step embedded Rust learning content with µFerris.
Applications/Project Builds 📱
Wireless sensor node — Combine a wireless XIAO (ESP32-C3/S3) with sensors to build an environmental monitoring device that pushes data over WiFi or BLE.
Security monitor — Expand the alarm clock project from Simplified Embedded Rust into a wireless security monitoring device.
Wireless data logger — Pair a XIAO Sense with a wireless XIAO to build a portable logging device.
Low-power applications — Explore sleep modes, power gating, and battery-powered operation on XIAO.
Edge AI — Deploy TinyML models leveraging XIAO sensors.
These are starting points. We want to see what you come up with.
