A Radar Scope on the Arduino UNO Q: Multi-Target Tracking with the Ai-Thinker RD-03D mmWave Sensor
UNO Q with a 24 GHz radar wired to the board to build a live radar scope - the MCU turns a binary sensor stream into three tracked targets, and the Linux side draws them sweeping across a web dashboard. Along the way, a proper look at how FMCW radar works, all showing the strength of mmWave radar.

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.
