Embedded Rustacean Issue 67 Rounds Up Embedded Rust News and Tutorials

The Embedded Rustacean dropped Issue 67 on March 13, 2026, delivering its latest bi-monthly roundup of everything moving in the embedded Rust world. For Rustaceans writing firmware, wrangling HALs, and pushing peripheral drivers to their limits, this digest has become a reliable gathering point: new releases, technical tutorials, HAL and peripheral driver news, and community updates all collected in one place.

What the Newsletter Covers

The Embedded Rustacean describes itself as a bi-monthly digest for developers working on embedded Rust, and Issue 67 continues that mission with its characteristic mix of content categories. The newsletter's stated focus spans new releases, technical tutorials, HAL and peripheral driver news, and community updates, covering the full spectrum from upstream crate announcements to the hands-on guidance that helps developers actually wire things together on real hardware. Whether you're tracking a new version of a display driver crate or looking for a walkthrough of a specific microcontroller peripheral, the digest pulls those threads into a single read.

It's worth noting that "bi-monthly" can mean different things depending on who's publishing, and the source material doesn't clarify whether The Embedded Rustacean publishes twice a month or once every two months. That cadence question is worth checking directly with the maintainers if you're planning your reading schedule around it.

The GitHub Ecosystem Behind the Newsletter

The Embedded Rustacean isn't just a newsletter: it's anchored by a GitHub account that functions as a resource hub for the embedded Rust community at every skill level. The account's welcome message sets the tone directly: "Welcome to The Embedded Rustacean GitHub Account! If you're passionate about embedded systems and Rust programming, you're in the right place. This repository is dedicated to providing you with valuable resources and repositories to support your learning journey as you transform into an embedded Rust developer."

Beyond the newsletter itself, the account points readers toward a blog covering tutorials and case studies related to embedded Rust development, and a store stocking books and resources curated specifically for embedded Rust developers. The combination of newsletter, blog, and store gives the project a layered presence, useful whether you want a quick weekly digest or a deeper dive into a specific topic.

Books for Getting Started

For developers new to embedded Rust, the GitHub account highlights two books as the recommended entry points:

• Simplified Embedded Rust: ESP32-C3 Standard Library Edition
• Simplified Embedded Rust: ESP32-C3 Core Library Edition

Both titles are oriented around the ESP32-C3, a popular choice for embedded Rust beginners given its strong community support and well-maintained HAL. The Standard Library Edition and the Core Library Edition represent two distinct approaches: one leaning on the standard library for a more ergonomic experience, the other going closer to the metal with the core library. Having both available under the same umbrella makes it easier to choose the path that matches your project constraints.

Repositories Worth Knowing

The GitHub account hosts a collection of repositories that mirror the breadth of the embedded Rust ecosystem. The most active by the numbers associated with each listing are:

• Rust projects and templates for the ESP32C3 (associated numeric tokens: 111, 9)
• Simplified Embedded Rust: Standard Edition Book Projects and Templates (96, 14)
• Rust projects and templates for the STM32Nucleo-F4 development board (67, 7, listed under C)
• Simplified Embedded Rust: ESP Core Edition Book Projects and Templates (58, 7)
• SH8601 Display Driver Crate (9, 6)
• RM690B0 Display Driver Crate (4, 1)

A quick note on those numbers: the source provides them as numeric tokens adjacent to each repository name but does not label what they represent. They may indicate stars, forks, open issues, or some combination, but that's not confirmed in the available data. The STM32Nucleo-F4 templates repository is also notable for being listed under C rather than Rust, which reflects the reality that embedded development often bridges the two languages even within a Rust-focused project.

The SH8601 and RM690B0 display driver crates are the smallest repositories by those unlabeled metrics but are worth watching. Display driver crates are a critical piece of the embedded Rust puzzle, and having dedicated crates for specific display controllers keeps the ecosystem from fragmenting into one-off, project-local implementations.

Getting Involved

The Embedded Rustacean community explicitly positions itself as open to contributors at every experience level. The GitHub account's invitation is direct: "We encourage you to contribute, share your ideas, and collaborate with us! Whether you're a beginner looking to learn or an experienced developer eager to contribute, there's something here for everyone."

That framing matters in embedded Rust, where the gap between beginner-friendly documentation and production-ready drivers can feel enormous. A project that actively cultivates both ends of that spectrum is doing real work for the ecosystem.

For staying current beyond Issue 67, the account points to its newsletter subscription for ongoing updates, the blog for longer-form case studies and tutorials, social accounts for real-time activity, and the store for curated learning materials. The newsletter subscription itself is the most direct line to future issues as they publish.

A Note on the Source

The research behind this piece is built on the newsletter's published description and a capture of The Embedded Rustacean GitHub account page. That page capture included some loading errors on the repository section, which means the numeric tokens and some repository details should be verified against the live page for the most current and fully labeled data. The specific content inside Issue 67, including any particular crate releases, tutorial titles, or HAL announcements highlighted in this issue, requires a direct read of the issue itself. The digest's consistent focus on new releases, technical tutorials, HAL and peripheral driver news, and community updates makes it a reliable tracker for anyone keeping pace with the embedded Rust space as it continues to mature.
