The OpenMV AE3: A Time-of-Flight Doorman for the NPU
Part two of the OpenMV series shrinks the board and the power to a quarter of a watt, while running YOLO. Built on Alif's Ensemble E3 with two Cortex-M55s and two Ethos-U55 NPUs, the AE3 also carries something its bigger sibling does not, a VL53L8CX 8x8 ToF depth sensor.

The OpenMV N6: A MicroPython Camera with a Real NPU
The OpenMV N6 pairs an 800 MHz Cortex-M55 with ST's 600-GOPS Neural-ART NPU and a removable global-shutter camera, and MicroPython - YOLO object detection at 30 fps, in Python, under a watt. We tour the hardware properly, walk through setup, and build a people-counting application on the NPU.

A Real Dual-Brain Application on the Arduino UNO Q: an AI Brick, a Camera, and a Presence Lamp
Part two of the UNO Q series puts the board's dual-brain design to real work - a vision AI Brick on the Linux side detects a person through a camera, and the microcontroller side turns that into a smoothly breathing lamp that never stutters, no matter how hard the AI is working.

Getting to Know the Arduino UNO Q: Two Brains, One Board, and Zephyr Underneath
The Arduino UNO Q pairs a quad-core Linux processor with a real-time STM32 microcontroller on one UNO-shaped board, and quietly runs Zephyr where the classic Arduino runtime used to be. This guide takes an engineer's look at the architecture.

The State of Rust for Embedded Development in Mid-2026
A survey of where Rust stands for embedded and edge development in mid-2026, from bare-metal async on microcontrollers to services on embedded Linux, including the toolchain, the safety-certification story, the wireless gaps, and measurements from this blog's own boards.

The Zephyr Web Server, Now in C++: Classes for Embedded Hardware
A short follow-on from the Zephyr Thread web server guide, rebuilding the same project in C++ on the Seeed XIAO nRF52840, and adding the RGB LED and the on-die temperature sensor to show why classes suit Zephyr hardware so well.

An Async Wi-Fi Web Server on the ESP32-C3 with Embassy and no_std Rust
This guide explains how Embassy ties an ESP32-C3 Wi-Fi web server together. It assumes you are comfortable with basic Rust (ownership, traits, match) but new to embedded async.
