If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

Like the Nano, the Micro's size and male pin headers make it perfect for prototyping with a breadboard. However, Arduino also offers this board without headers pre-soldered.

This board also features 128 MB of RAM, 8MB of Flash and the usual compliment of Arduino pins in a Leonardo-compatible layout. Also on the SoC is a PCIE bus, Ethernet, a USB 2.0 host, and an SD card.

Arduino enthusiasts may be interested in a new thumb-sized radio-equipped Arduino Leonardo development board created by Doug Lyon.

V-USB (Virtual USB) is especially useful for those of us who build standalone Arduino projects with the ATMEGA328. Unlike the Arduino Leonardo and its ATMEGA32U4, the ATMEGA328 does not have a ...

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16 MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84 MHz processor, while augmenting inputs ...

LittleBits fixes this with the Arduino Bit ($39.95), an Arduino Leonardo-based microcomputer built into a three-input, three-output LittleBits module.

One Leonard-Micro difference is with the ‘built-in’ led. In the Leonardo, an op-amp between the ATmega pin and the led means that loading is minimal and the pin can easily be used as an Arduino input.

The small IMUduino Arduino Leonardo powered board is currently the world’s smallest Arduino Leonardo compatible board that includes integrated wireless motion and orientation sensing technology.
