Embedded Firmware in Rust

Firmware that works, and stays maintainable

Firmware is often the invisible foundation of your product. Until it fails. Random crashes, unexplainable behavior, a codebase no one dares to touch anymore. We build firmware that is reliable and stays maintainable, in Rust.

Sound familiar?

  • Your firmware is fragile: every change breaks something else
  • Random crashes you can't reproduce
  • The codebase has become a black box, even for your own team
  • Your firmware developer left and no one understands the code
  • It works, but you're afraid to change anything
  • You want to add new functionality, but it feels like a minefield

We build firmware you can build on. Literally.

Why Rust?

Not because it's new, but because it produces better firmware.

Fewer bugs

Entire categories of errors, like null pointers, buffer overflows, and race conditions, simply don't exist in Rust. The compiler catches them before your code runs.

Understandable code

Rust forces you to make explicit choices. That makes code more readable, even for those who join later.

Long-term maintainability

Make changes without fear. The compiler tells you what breaks, before you test it on hardware.

Modern tooling

Dependency management, testing, debugging: it just works. No loose scripts and manual configurations.

We've been working with Rust on embedded for five years now. We're more productive in it than in C, and the quality is higher.

What we do

New firmware

From scratch, on your hardware or on a platform we choose together. Clean architecture, built to grow with you.

Firmware with PCB design

We also design hardware. When we do both, they're aligned from the start.

Firmware on existing hardware

You already have a PCB, your own or from a third party. We write the firmware that runs on it.

How we work

Pragmatic

We build what you need. No over-engineering, no tech for the sake of tech.

Direct lines

You talk to the engineers who write the code. No intermediaries.

Knowledge transfer

We document what we build and explain why. You don't stay dependent on us.

What you get

  • Firmware that does what it should, reliably
  • Code that is readable and maintainable
  • Documentation that helps your team move forward
  • Optional: guidance for further development yourself

Prefer firmware in C?

That's possible too. We have extensive experience with C on embedded.

To be honest: a C project typically takes more time than the same project in Rust. Not because we know C less well, but because it requires more discipline and testing to achieve the same quality. That's reflected in the price.

Do you have an existing C codebase you want to extend or maintain? Then C is often the logical choice. For new projects we recommend Rust, but the choice is yours.

About us

Jitter has been working with Rust on embedded systems for five years, primarily on STM32. We've gone through the learning curve and know where the pitfalls are. We put that experience to work for your project.
