LTC3895 – Step-down controller handles 150 V
https://www.electronics-lab.com/step-down-controller-handles-150-v/
Linear Technology Corporation announces the LTC3895 , a high voltage non-isolated synchronous step-down switching regulator controller that drives an all N-channel MOSFET power stage. Its 4V to 140V (150V abs max) input voltage range is designed to operate from a high input voltage source or from an input that has high voltage surges, eliminating the […]

https://www.electronics-lab.com/pressure-temperature-humidity-sensor-board/
Mare shares his sensor board based on MS5637 HDC108. He writes: This is another small module to measure air pressure, temperature and humidity. Two sensors are on-board: MS5637 and HDC1080. Microcontroller is small cortex M0 in TSSOP-20 housing from STM: STM32F070CxP. The SN65HVD72DGKR provides RS485 interface functionality with half duplex mode. Voltage regulator, reverse polarity […]
Project curve tracer – progress update
https://www.electronics-lab.com/project-curve-tracer-progress-update/
Jason Jones has been working on a curve tracer project and shows us his June progress: As the hardware is at the point of initial release, but the firmware and GUI aren’t quite there yet, I decided that it would be prudent to split off the firmware and GUI components into their own GIT repositories. […]

Dan Watson writes: This is the second in a series of posts about designing a mains frequency monitor using the Microchip PIC 16F1619 microcontroller. In this post we will take a look at the first revision of the board that I designed for the project and some of the features that it adds. Be sure […]
How to Build a Control Circuit with Adjustable Working Time via Wi-Fi
https://www.electronics-lab.com/build-control-circuit-adjustable-working-time-via-wi-fi/
In this article, you’ll learn how to build a system that can turn DC loads on and off using a mobile application. You’ll also learn how to perform this task via immediate actions or via timers set in advance for switching loads on and off. by Yahya Tawil You can implement this system in environments […]
Arduino Uno Menu Template
https://www.electronics-lab.com/arduino-uno-menu-template/
PaulSS @ instructables.com shows us how to build a menu for a LCD/button shield: While working on a new Instructable (coming soon) I had decided to use an Arduino Uno with an LCD/button shield I purchased off of AliExpress. It’s a knockoff of the DFRobot Shield. I knew that I needed a menu for my […]
