It has a form factor that enables it to be easily placed on a breadboard.The Arduino Nano is a small, complete, and breadboard-friendly board based on the. It contains everything needed to support the microcontroller simply connect it to a computer with a micro USB cable to get started. It has 20 digital input/output pins (of which 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.

This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. USB.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. Arduino Nano Board LayoutAlso, as opposed to Arduino Nano boards that support 5V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the. Personally speaking, I suggest Arduino Nano over UNO as it is cheaper, breadboard friendly, small in size and has couple of more pins (digital and analog IO) than UNO.

For details, see the referenceВ and tutorials.The ATmega32U4 on the Micro comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. Select 'Arduino/Genuino Micro from the Tools > Board menu. WarrantyYou can find here your board warranty information.The Micro board can be programmed with the Arduino Software (IDE). Need any help with your board please get in touch with the official Arduino User Support as explained in our Contact Us page.

The power source is selected automatically.External (non-USB) power can come either from a DC power supply or battery. PowerThe Micro can be powered via the micro USB connection or with an external power supply. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. WarningsThe Micro has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent.

The regulated power supply used to power the microcontroller and other components on the board. You can supply voltage through this pin. The input voltage to the MICRO board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). The recommended range is 7 to 12 volts. If using more than 12V, the voltage regulator may overheat and damage the board. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may become unstable.

It also has 2.5 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library). Maximum current draw is 50 mA.The ATmega32U4 has 32 KB (with 4 KB used for the bootloader). A 3.3 volt supply generated by the on-board regulator.

TWI: 2 (SDA) and 3 (SCL). Note that on the Micro, the Serial class refers to USB (CDC) communication for TTL serial on pins 0 and 1, use the Serial1 class. Used to receive (RX) and transmit (TX) TTL serial data using the ATmega32U4 hardware serial capability. Serial: 0 (RX) and 1 (TX). A maximum of 40mA is the value that must not be exceeded to avoid permanent damage to the microcontroller.In addition, some pins have specialized functions: Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor (disconnected by default) of 20-50 k ohm.

SPI: on the ICSP header. Provide 8-bit PWM output with the analogWrite()В function. PWM: 3, 5, 6, 9, 10, 11 and 13. See the attachInterrupt()В function for details. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. External Interrupts: 0(RX), 1(TX), 2, 3 and 7.

When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. There is a built-in LED connected to digital pin 13. It is connected to the RX_LED that indicates the activity of transmission during USB communication, but is can also used as slave select pin (SS) in SPI communication. RX_LED/SS This is an additional pin compared to the Leonardo. Note that the SPI pins are not connected to any of the digital I/O pins as they are on the Uno, they are only available on the ICSP connector and on the nearby pins labelled MISO, MOSI and SCK.

The chip also acts as a full speed USB 2.0 device, using standard USB COM drivers. The ATmega32U4 also allows for serial (CDC) communication over USB and appears as a virtual com port to software on the computer. The 32U4 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). Typically used to add a reset button to shields which block the one on the board.The Micro has a number of facilities for communicating with a computer, another board of the Arduino & Genuino family, or other microcontrollers. Bring this line LOW to reset the microcontroller. Used with analogReference().

Automatic (Software) Reset and Bootloader InitiationRather than requiring a physical press of the reset button before an upload, the Micro board is designed in a way that allows it to be reset by software running on a connected computer. The layout allows for easy placement on a solderless breadboard. Physical CharacteristicsThe maximum length and width of the Micro PCB are 4.8cm and 1.77cm respectively, with the USB connector extending beyond the former dimension. For SPI communication, use the SPI library.The Micro appears as a generic keyboard and mouse, and can be programmed to control these input devices using the Keyboard and Mouse classes. The Arduino Software (IDE) includes a Wire library to simplify use of the I2C bus see the documentationВ for details. The RX and TX LEDs on the board will flash when data is being transmitted via the USB connection to the computer (but not for serial communication on pins 0 and 1).A SoftwareSerial libraryВ allows for serial communication on other Micro's digital pins.The ATmega32U4 also supports I2C (TWI) and SPI communication.

If the software can't reset the board, you can always start the bootloader by pressing the reset button on the board. Note that when the board first powers up, it will jump straight to the user sketch, if present, rather than initiating the bootloader.Because of the way the Micro handles reset it's best to let the Arduino Software (IDE) try to initiate the reset before uploading, especially if you are in the habit of pressing the reset button before uploading on other boards. The bootloader can also be initiated by pressing the reset button on the Micro. After the processor resets, the bootloader starts, remaining active for about 8 seconds. When this happens, the processor will reset, breaking the USB connection to the computer (meaning that the virtual serial / COM port will disappear).
