What if the future of IoT didn’t depend on Wi-Fi? Imagine deploying a fleet of sensors in the remotest corners of the world, tracking wildlife, monitoring environmental changes, or managing logistics, ...

The Federal Communications Commission (FCC) recently published a 163-page PDF showing the electrical schematics for the iPhone 16e, despite Apple specifically requesting them to be confidential. This ...

An isolated DC-DC converter board based on the flyback topology. In this video, we walk through the design, layout, and testing of an isolated DC-DC converter board based on the flyback topology. With ...

Abstract: A differentially fed Yagi-Uda antenna with a folded dipole active element fabricated on a 10-layer printed circuit board (PCB) is demonstrated for 57-64 GHz short-range communications. The ...

Abstract: The co-design, fabrication and characterization of an active D-band antenna array with large bandwidth for use in next-generation, high-speed wireless systems is presented. A ...

There are plenty of small ESP32-C3 IoT boards with a USB-C connector on the market, and while they all look very similar, antenna designs differ, and less thought-out ones may severely impact the WiFi ...

Thanks to an innovative extension to 3D printing, researchers can create high-performance, low-weight “unbuildable” RF structures that combine dielectrics and patterned conductors. The benefits and ...

The QuadClock PCB is an ESP32-S3-powered multi-display clock controller designed to serve as a foundation for creating a four-TFT-display clock. It supports up to four 1.69-inch rectangular TFT ...

For smaller size, you might want to consider the ESP32-Devkit module which has only 30 pins vs. 38 pins on the ESP32-WROOM. I thinks it's also a little cheaper. This should require only a trivial ...

Why harvesting low-level RF is difficult. How a new spin-rectifier implementation addresses a major limitation. The results achieved with the new component. Energy harvesting has lots of positive ...
