Arduino Micro clone is a more practical version of the Arduino Leonardo in a very small version 4.8 x 1.8 cm. Just like the great forerunner here we find the controller ATmega32u4. This advanced chip contains a built-in USB communication. Therefore, it can be controller to operate as a HID device (such as a mouse or a keyboard) and as a virtual COM interface. Start you facilitate the examples supplied with the software Arduino.

The card connects to your computer with a simple USB cable. This connection allows two-way communication and at the same time powers the controller. This makes it entry into the world of microprocessors simple. A special version of the Arduino Micro allows you to plug the controller to the wiring board. The connection to the 20 input/output pins (of which can be used 7 as PWM and 12 as analog inputs) is due to the fact very clear. Processor with a speed of 16 MHz and 32 Kb flash memory (4 KB it occupies bootloader) represent a sufficient source for large projects.

Warning: the Software is only in EN or DE language version.
