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.

Turning an Arduino of virtually any sort into a simple AVR 6-pin ISP programmer is old hat. But when Atmel came out with a series of really tiny AVR chips, the ATtiny10 and friends with only six pins ...

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 ...

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 ...

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 ...

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 ...

Arduino the makes of the popular development boards has this month launched a new miniature version of its Arduino Yun board in the form of the aptly named Arduino Yun Mini. Arduino Yun Mini is a ...

We may receive a commission on purchases made from links. As technology has advanced, the types of ports on computers have also changed for the better. However, that doesn't mean devices with older ...

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 ...
