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.

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Arduino ...

PD Micro is the first Arduino-compatible board with USB Type-C Power Delivery, which allows your project to make use of voltages from 5-20 V. It’s perfect for projects that would require separate ...

Developers, makers and electronic enthusiasts searching for a small Arduino development board may be interested in the aptly named Atto. A small affordable USB development board designed specifically ...

Arduino has announced the new UNO R4 board family, a new platform for enthusiasts, hobbyists, students, and professionals to create prototypes, innovative solutions, and other interactive electronic ...

Modern operating systems insulate us — as programmers, especially — from so much work. Depending on how far back you go, programmers had to manage their own fonts, their own allocation space on mass ...

In Part I of this article, I briefly mentioned the generic USB driver in the context of getting a USB device to communicate through it easily, with no custom kernel programming. Unfortunately, I ...

If you are a software and hardware developer working with serial ports, you often need a reliable serial port monitor that allows you to capture, display, analyze, record, and replay all serial port ...

In my last column [see LJ December 2002], we covered the serial layer in the 2.5 (hopefully soon to be 2.6) kernel tree. We mentioned in passing that a USB-to-serial driver layer in the kernel helps ...
