The Arduino Micro is a microcontroller board based on the ATmega32u4, developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard. The Micro is similar to the Arduino Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial/COM port. It also has other implications for the behavior of the board. * ATmega32u4 microcontroller * Operating Voltage 5V * Input Voltage 7 to 12V * Digital I/O Pins 20 (of which 7 provide PWM output) * Analog Input Pins 12 * DC Current per I/O Pin 40mA * DC Current for 3.3V Pin 50mA * Flash Memory 32 KB (of which 4 KB used by bootloader) * SRAM 2.5 KB * EEPROM 1 KB * Clock Speed 16MHz https://elecena.pl/product/27276318/arduino-micro-a000053-board 2024-11-14 https://elecena.pl/product/27276318/arduino-micro-a000053-board 2025-04-10 https://elecena.pl/product/27276318/arduino-micro-a000053-board 2025-05-11 https://elecena.pl/product/27276318/arduino-micro-a000053-board 2025-06-17 https://elecena.pl/product/27276318/arduino-micro-a000053-board 2025-09-04 https://elecena.pl/product/27276318/arduino-micro-a000053-board 2026-03-02 https://elecena.pl/product/27276318/arduino-micro-a000053-board 2026-03-25 https://elecena.pl/product/27276318/arduino-micro-a000053-board 2026-04-17
