From the Wemos D1 mini to the NodeMCU, the ESP8266 based boards are by far the most popular platform, among makers and hobbyist, for building WiFi based projects due to their low cost and general ease of use.  For today’s tutorial, we will continue our exploration of the most popular...

Coilcraft will introduce its new XGL4020 Series of high-performance, molded power inductors at the upcoming Applied Power Electronics Conference (APEC), March 17-21 in Anaheim, CA. The XGL4020 features the industry’s lowest DC losses and extremely low AC losses for a wide range of...

Like previously marketed boards of Raspberry, this new module is not meant for the traditional use. Rather, business and industrial use were intended with the New Raspberry Pi Compute Module 3+. Keeping the same compatibility, Raspberry new boards are the modern version of computing...

Weather stations are interesting projects for beginners and very useful for expert makers. They are usually quite simple to build but also provide fairly accurate and useful weather data. We have built a couple of them in different tutorials on this website, with the difference usually...

This project describes how to build an ATSAMD21-based computer on a prototyping board using the minimum number of components, and program it from the Arduino IDE. David Johnson-Davies writes: I give two alternative methods of uploading a bootloader to the bare ATSAMD21 chip using the...

This application note explains the step-up circuit using a bootstrap capacitor. In buck converters, this circuit is used when the high-side switch is the N-ch MOSFET. The configuration of the circuit in proximity to a buck converter depends on the polarity of the high-side switch.When...

The emerging trend of smart lighting and Internet of Things, requires a new generation of LED drivers. Infineon Technologies AG introduces the new member of its XDP LED series, the XDPL8221 for cost-effective dual-stage drivers with advanced features. This device combines a...

Shenzhen Wesion has recently launched Khadas VIM2 v1.4 with various improvements they neatly describe in a PDF document. Currently there are three versions of Khadas VIM2 (v1.2) boards: VIM2 Basic – 2GB DDR4, 16GB eMMC flash, Ampak AP6356S wireless module with 802.11 b/g/n/ac...
