A000053 Arduino MICRO 5V

<p>The Micro is a microcontroller board based on the ATmega32U4 (datasheet), developed in conjunction with Adafruit. It has 20 digital input/output pins (7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz 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. Its form factor allows it to be easily placed on a breadboard.</p> <p>The Micro board 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.</p> <h2>Key Features:</h2> <ul> <li><strong>Microcontroller:</strong> ATmega32U4</li> <li><strong>Operating Voltage:</strong> 5V</li> <li><strong>Input Voltage (Recommended):</strong> 7-12V</li> <li><strong>Digital I/O Pins:</strong> 20</li> <li><strong>PWM Channels:</strong> 7</li> <li><strong>Analog Input Channels:</strong> 12</li> <li><strong>DC Current per I/O Pin:</strong> 20 mA</li> <li><strong>DC Current for 3.3V Pin:</strong> 50 mA</li> <li><strong>Flash Memory:</strong> 32 KB (ATmega32U4) of which 4 KB used by bootloader</li> <li><strong>SRAM:</strong> 2.5 KB (ATmega32U4)</li> <li><strong>EEPROM:</strong> 1 KB (ATmega32U4)</li> <li><strong>Clock Speed:</strong> 16 MHz</li> <li><strong>LED_BUILTIN:</strong> 13</li> <li><strong>Length:</strong> 48 mm</li> <li><strong>Width:</strong> 18 mm</li> <li><strong>Weight:</strong> 13 g</li> </ul>
