Giving Claude Code a Logic Analyser: A Minimal Bench Harness for Zephyr on the nRF52840
An AI coding agent can write, build and flash firmware, but it cannot see the LED. This article builds a small Claude Code harness for Zephyr on the nRF52840 DK that closes the loop with real measurements from an Analog Discovery, and shows what it caught that reading the code never would.

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.

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.
