Inside is Arduino Pro Micro and a PMW 3389 optical sensor on a breakout board. [Ben] was going to use flexible 3D printed panels as mouse buttons, but then had an epiphany — why not use keyboard ...

The Micro measures 48 mm in length and 18 mm in width and weighs about 13 g. The Nano, on the other hand, comes in the smallest form factor Arduino offers, with the same 18 mm width but a shorter ...

With surface-mount technology pushing the size of components ever smaller, even the most eagle-eyed among us needs some kind of optical assistance to do PCB work. Lots of microscopes have digital c… ...

The Arduino Micro will be available exclusively through Radio Shack and Adafruit first before becoming more widely available next month. The board is available with headers for €21 (roughly $27 ...

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 ...

The Arduino micro controller can be easily removed from the robot, and it is placed on the prototyping board so that you can program to your heart's content. It easily connects to a PC or laptop ...

Except, on the Micro, there is no actual serial bus involved in programming the Arduino, as everything is done over USB. So the TX and RX leds are driven by a couple of pins on the ATmega32U4 (see a ...

But it's possible to go even smaller, as the makers of a new Arduino-compatible product called "Microduino" show. At 1" × 1.1", it's nearly as small as a quarter.
