Watching the Scheduler Work This article is part of a series on RTOS fundamentals with the ST Nucleo-F401RE: - Zephyr from zero: the toolchain, the board, and the scheduler on a scope – this article - The same demo in async Rust with Embassy (coming soon)…

Tracking with the low-cost RD-03D mmWave Sensor This article is Part 4 of a series on the Arduino UNO Q: - Getting to know the UNO Q: two brains, one board, and Zephyr underneath - A real application: an AI Brick, a camera, and a presence lamp - Under the…

Why Your LED Is On When You Told It Off: The Zephyr Devicetree, Explained Here is a puzzle that has cost students many beginner-hours: You write a line of code that means "turn the LED off".

Vanilla Zephyr on the UNO Q Cortex-M33 This article is part 3 of a series on the Arduino UNO Q: 1.

Named after Charlie Allen, who wrote it up in a Maxim application note in the early 2000s.

The AE3: A ToF AI Doorman for the NPU This article is Part 2 of multi part series on OpenMV's new generation of AI cameras: - The OpenMV N6: a MicroPython camera with a real NPU - This guide: the OpenMV AE3, and letting a depth sensor decide when to think…

A MicroPython Camera with a Real NPU 💡 This article is Part 1 of a two-part series on OpenMV's new generation of AI cameras: - This guide: the OpenMV N6, the flagship - The OpenMV AE3: machine vision on a battery budget The series stands alone, though rea…

A Real Dual-Brain Application on the Arduino UNO Q 💡 This article is Part 2 of a series on the Arduino UNO Q:Getting to know the UNO Q: two brains, one board, and Zephyr underneath.

Getting to Know the Arduino UNO Q To my mind, the Arduino UNO Q is the most architecturally interesting board Arduino has ever shipped, and the interest starts before you open the box.

Rust for Embedded Development in Mid-2026 Two of the boards on my desk are running Rust as I write this.

From TinyML to Tiny Language Models: the State of Edge AI in 2026 There is a small pile of circuit boards on my desk, and between them they tell you most of what has happened in applied edge machine learning over the last few years.

💻 This article is part of a series built around the Seeed XIAO nRF52840 and a Thread mesh: A web server in async Rust on the ESP32-C3, over Wi-FiThe same server in C on Zephyr, over Thread — this is its C++ companion In the previous guide we built a small…

In an earlier guide we built a tiny web server on an ESP32-C3 in async Rust, using Embassy.
