🎁 Bundle deal — order both boards with Simplified Embedded Rust & get 20% off

Learning embedded Rust shouldn't mean fighting your hardware. Every tutorial picks a different board, a different MCU, a different toolchain — so half the battle is just making the example compile on the silicon you happen to own.

uFerris is one reference platform that works across multiple MCUs. Swap the brain on top, keep the peripherals underneath. Focus on Rust, not on rewiring your dev setup.

One board, many MCUs — Seeed XIAO header accepts ESP32-C3 / C6 / S3, RP2040, RP2350, nRF52840, SAMD21, RA4M1, and more

Every standard peripheral on board — GPIO, timers/counters, ADC, PWM, UART, I²C, SPI — no breadboard required

Build a complete embedded product replica — sensors, actuators, display, storage, battery

A single reference for the Embedded Rust ecosystem — book, examples, and BSP crate all target this hardware

Fully open source — schematics, board files, and the BSP crate are all public. Fork it, modify it, learn from it, contribute to it.

The standalone learner board. Onboard components cover every standard peripheral you’ll meet in embedded development. Drop in a Seeed XIAO module to pick your MCU and start coding.

uFerris Megalops Power Extension Board - $14.99

Cuts the USB cord. 2×AAA battery holder, onboard current-measurement circuit (so you can see exactly how much your firmware sips), and a microSD slot for SPI exercises and data logging. Stacks directly onto the Megalops Baseboard.

Built for Learning

uFerris is fully integrated as the hands-on companion for the Simplified Embedded Rust series. Both the ESP Core Library Edition and the ESP Standard Library Edition. Every chapter, every example, every project, designed to work on uFerris.

uFerris is open source, top to bottom. The hardware design, the firmware, and the supporting Rust crates are all public. You can study them, learn from them, fork them, or contribute back.

uFerris is certified by the Open Source Hardware Association — UID JO000001. The first OSHWA-certified project from Jordan. Certification page: https://certification.oshwa.org/jo000001.html

Hardware Repository: schematics, board files, BOM, and gerbers.

Board Support Package (BSP) Repository: board support crate source code, board coverage, and example code. Issues, pull requests, and discussions are welcome on all repos.

BSP Crate: board support crate on crates.io.

Working on a piece to review uFerris? We’re happy to provide review units, a press kit, and technical Q&A. uFerris is fully open source. Schematics, board files, and the Rust BSP are all public, so you’re welcome to dig in before pitching.
