New tools make AI work on microcontrollers

Embedded AI struggles with PyTorch’s heavy models, but an open-source push led by Meta, Arm, and Alif uses ExecuTorch to shrink and adapt AI models for Arm Ethos NPUs inside Alif’s MCUs, unlocking real edge intelligence.

All your dev kits in one place

Farnell’s DevKit HQ is an online platform where you can discover and compare development kits and boards by application, with access to software demos, modular solutions, data sheets, and training materials for faster project progress.

Brain-like chip speeds up neural analysis

Using a brain-like architecture, this chip rapidly decodes the brain’s neural network connectivity, making it possible to analyse many neuron signals quickly and accurately.

How jumpers can change your circuit’s behaviour

By adding jumpers, whether simple wires, cap connectors, zero-ohm resistors, or solder bridges, you can switch between PCB variations or set semi-permanent configurations without redesigning the board.

How eFuses protect car electronics

Discover how eFuses provide smarter defence against common automotive shorts by using FETs to tackle issues diodes can’t fully solve.

RF connectors evolving for tighter, faster connections

As wireless tech advances, RF connectors evolve to maintain signal integrity on smaller PCBs and at higher frequencies. From tiny U.FL connectors to rugged SMA designs, they reduce loss and improve impedance matching for seamless communication.

PROJECTS & TUTORIALS

Create a Wi-Fi web server on Wio Terminal

Transform the Wio Terminal into a compact IoT server that hosts a sleek dashboard with live sensor readings and interactive screen colour control, using embedded C++ and modern web design.

Using ESP32 software timers with FreeRTOS

Learn how to set up and use FreeRTOS software timers on the ESP32 with Arduino IDE, including both periodic and one-shot timers, with clear examples to help you schedule tasks easily.

Build a flight motion recorder with ESP32

This project turns an ESP32 and a 6-axis BMI160 sensor into a mini flight recorder that continuously monitors motion events like free-falls and impacts, displaying results on both an onboard OLED and a real-time web dashboard.

Quick AI prototyping with PSoC 6 and Arduino

Bring your RPi chatbot to life

Using a Raspberry Pi 5, you can build an animatronic chatbot featuring independently moving eyeballs on universal joints, eyelids operated by a separate servo for natural blinking, and a Neopixel mouth that lights up in time with speech.

PIR sensor with esp32 interrupts and timers

This project shows how to combine interrupts and timers in Arduino IDE for motion detection. You’ll set up a PIR motion sensor to trigger an interrupt on an ESP32, which starts a timer to switch on an LED for a set time.

PRODUCTS

Learn transistor basics with hands-on circuits

This kit uses a colour-coded breadboard and a Pixie helper to guide you through building resistor-transistor logic circuits. The full-colour manual walks you step-by-step with schematics, push-button inputs, and LED outputs to explore everything from simple gates to memory latches.

STM32V8 hits new speed records with Cortex-M85

The STM32V8 is the first Cortex-M85 MCU built on 18-nm tech with 4 MB phase-change memory, running at 800 MHz to break 5,000 CoreMark points. Its Helium tech boosts AI and DSP tasks, making it up to six times faster than STM32H7 for computer vision.

Kyocera’s tiny clock oscillator runs on ultra-low voltage

Kyocera’s KC1210A series clock oscillators operate at a low 0.9 V and fit into a tiny 1.25 mm by 1.05 mm footprint, helping designers reduce power and size in smartphones, VR headsets, and harsh-temperature sensors.

Growing demand for advanced motor drivers

As electric vehicles and industrial robots use more motor drivers, the market pushes for higher efficiency and easier integration with different motors and control algorithms. This trend, powered by Industry 4.0 and smart electronics, is set to grow steadily over the next decade.

Renesas sets new DDR5 speed record

Renesas introduces its Gen6 DDR5 registered clock driver, the RRG5006x, which breaks previous speed limits by delivering 9,600 MT/s and helps match memory bandwidth with faster CPUs.

ESP32-H2-MINI-1 module with low-power monitoring

With a single-core 96 MHz RISC-V CPU, the ESP32-H2-MINI-1 supports Bluetooth LE and IEEE 802.15.4. It includes I2C, SPI, UART, ADC, PWM, and up to 19 GPIOs for versatile IoT projects. Oh, and Adafruit are selling this for just $2.25!!!
