“Supplino is a Quick & Dirty PSU (Power Supply Unit) made with some widely available breakout boards, an Arduino Nano (or an Arduino Nano Every) and a graphical LCD. Power output is given by a DC/DC ...

Recently I bought a few portable power supply devices to run my little microcontroller projects. There are countless variants of portable power supply devices that can be used to power up most ...

This file type includes high resolution graphics and schematics when applicable. Let’s face it: Some lucky folks don’t have to worry too much about power conversion. Just plug the board into the ...

If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...

Economy of scale is a wonderful thing, take the switch-mode power supply as an example. Before the rise of the PC, a decent multi-voltage, high current power supply would be pretty expensive. But PCs ...

USB-C Power Delivery 3.0 (PD3.0) introduces a new Programmable Power Supply (PPS) mode, which allows a device to negotiate any supply of 3.3-21 V in 20 mV steps, and up to 5 A of current in 50 mA ...

I got a couple of INA 219 modules from an online seller overseas. I was looking for a different dc current sensor module to start a small battery charger project, so I welcomed them. The INA219 based ...

Small solution sizes and high integration levels are required for extremely space-constrained systems, such as optical modules and solid-state drives (SSDs). While integrated power modules tend to be ...
