NEWS & ARTICLES
Meet the Seeeduino XIAO ESP32-C5, the first XIAO board to offer dual-band WiFi 6 by supporting 2.4 GHz and 5 GHz, marking a big step up from earlier ESP32 chips limited to 2.4 GHz.
MicroPythonOS runs on ESP32 and other MicroPython platforms, offering a fast, lightweight Android-like touchscreen interface with gestures, an app store, WiFi management, and OTA updates—all built natively in MicroPython.
Chips with billions of transistors are making systems safer around humans, devices smaller and smarter, and AI more common, shaping the technology of tomorrow.
Strain gauges work well for low-frequency torque measurement if you can manage installation details, while torque sensors deliver stable accuracy and dynamic response for fast, repeatable testing and production environments.
Unlike energy-heavy silicon or unstable perovskite, kesterite solar cells rely on abundant materials like tin and sulfur, making them more sustainable and scalable. Researchers are pushing its efficiency and durability to make it a commercially viable, eco-friendly solar option soon.
Whether you’ve noticed it or not, avrdude is the utility that communicates with AVR microcontrollers to upload code and manage device states, working behind the scenes in Arduino and similar tools.
As electronics demand slimmer, more intricate flex PCBs, manufacturers are gradually adding automation and data-driven tweaks to their workflows, enhancing quality and efficiency while keeping engineering know-how at the core.
PROJECTS & TUTORIALS
Build a professional Raspberry Pi weather dashboard that shows a 5-day forecast and a dynamic meteogram on the Elecrow Pi Terminal, giving you quick insights into temperature, air pressure, and precipitation trends.
The ESP32 goes way beyond blinking LEDs, powering projects like encrypted off-grid messaging, a smartwatch with step tracking, full-body VR leg tracking, high-quality audio streaming, and a wall touchscreen controller with MQTT integration.
Learn how to create a digital weighing scale by connecting a load cell with an HX711 module to an Arduino, calibrate it properly, and then display weights on an LCD with a button to reset the scale to zero.
Follow this complete guide to build an Arduino-powered robot that autonomously follows a marked path by sensing lines on different surfaces.
This guide walks you through 10 quick Raspberry Pi projects you can build in under an hour without extra hardware. This includes turning a Pi into a retro gaming console, network-wide ad blocker, internet speed monitor, home media centre, smart printer server, Minecraft server, and video capture/streaming station.
Learn to connect the TM1637 4-digit 7-segment display to your ESP32 using Arduino IDE, including wiring details and code for displaying a clock and temperature.
Use an ESP32 and DHT22 to record temperature and humidity every 2 seconds, tagging each reading with a clear NTP timestamp and saving it all to a microSD card as a CSV file.
LTspice lets you easily import third-party device models using either .MODEL directives or .SUBCKT blocks, so you can simulate components not in its default library.

Tria’s new OSM-LF-IMX95 module brings high-performance AI and vision capabilities to a small 45 × 45 mm package, using NXP’s i.MX 95 processor to deliver secure, flexible computing for embedded and edge applications.
With pin-to-pin AVR compatibility, integrated touch and ADC, plus Cortex-M0+ cores, the PIC32CM PL10 MCUs offer a low-cost, low-power solution that offloads tasks from the CPU for better real-time control.
Designed for powered tailgates and sliding doors, Toshiba’s TB9104FTG gate driver IC uses an SPI interface plus optional PWM inputs to control multiple brushed DC motors, cutting down on wiring complexity and MCU processing with its built-in PWM clock circuits.
The BD9xxN5 LDO regulators from Rohm deliver 500 mA output current with low 25 μA consumption, using Nano Cap tech to work reliably with very small output capacitors in 12 V and 24 V systems.
The BT110 lets you craft sounds by applying maths and logic operations to a variable, feeding the result through a DAC. Its visualiser reveals how each function changes the byte output, and exposed pins invite you to expand the module with things like video or extra inputs.
There’s a growing variety of AI chips for edge devices, spanning ultra-low-power speech tasks to powerful models that run vision and language functions locally.
