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 ...

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 ...

That initiative puts forward a Wi-Fi capable board for Arduino projects that permits wireless programming and the ability to interface with Web services. The company originally asked for $10,000 ...

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 ...

Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V. USB connector changed to Type-C. 6 – ...

The project takes an MRFC-522 RFID module and explains how to interface it to an Arduino. In this case the Arduino in question is an Arduino Pro Micro chosen for its ability to be a USB host.
