Expanding its range of embedded-core DC/DC converters, Murata Power Solutions adds the NXF1 series of regulated, high isolation converter with 3.3 or 5.0V outputs. Inputs available are nominal 3.3 and 5.0V in an industry-standard, surface-mount package with a low profile of 5.1mm. Line...

4 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 4 relays for switching applications in your project. Very compact design that can fit on top of Arduino UNO. Project requires 12V DC supply, all 4 trigger inputs require TTL signal, Relay-1 to Relay-4...

Hi guys, in one of our previous tutorials, we built a real-time clock with temperature monitor using the DS3231 and the 16×2 LCD display shield. Today, we will build an upgrade to that project by replacing the 16×2 LCD display with an ST7735 based 1.8″ colored TFT display. Apart...

David Johnson-Davies published another great tutorial on how to use the Tiny Graphics Library to plot the outside temperature over 24 hours on a 128x64 OLED display using an ATtiny85. This small graphics library provides point, line, and character plotting commands for use with an I2C...

Arduino just announced a new Yun v2 Board with improvements over the older brother. From the Arduino blog: What’s New in Rev.2 Hardware: Much better, more robust power supply New Ethernet connector with a clever mounting solution that enables the use of all possible...

by Marian Stofka @ www.edn.com: The bq25504 from Texas Instruments is a good candidate to become a milestone on the road to micro-power management and energy harvesting. A prominent feature of this IC is its ability to start up at a supply voltage as low as 330 mV typically, and 450...

Melexis' next-generation monolithic magnetic sensor family, consisting of the MLX90371 and MLX90372, provides robust absolute position sensing for various applications. By Julien Happich @ eenewseurope.com: Both devices consist of a Triaxis Hall magnetic front end, an analog to digital...
