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 ...

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 ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

The PC power supply has been a standard of the junk box for the last couple of decades, and will probably continue to be for the foreseeable future. A product that is often built to a very high ...

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, ...
