Для информации:

Overview The Iteaduino Leonardo is a microcontroller board based on the ATmega32u4 it's 100% compatible with Arduino Leonardo. It has 20 digital input/output pins a 16 MHz crystal oscillator a micro USB connection a power jack an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. The Iteaduino Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication eliminating the need for a secondary processor. This allows the Leonardo 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. Features Efficient DC-DC Power supply with wide range input 3.3V/5V Operating Voltage selection All pins out for Sensor and Servo UART/IIC interface breakout Power Supply The Arduino Leonardo can be powered via the micro USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The board can operate on an external supply of 7 to 23 volts. If supplied with less than 7V however the 5V pin may supply less than five volts and the board may be unstable. The power pins are as follows: VIN. The input voltage to the Iteaduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin or if supplying voltage via the power jack access it through this pin. 5V. The regulated power supply used to power the microcontroller and other components on the board. This can come either from VIN via an on-board regulator or be supplied by USB or another regulated 5V supply. 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 250 mA. GND. Ground pins. IOREF. The voltage at which the i/o pins of the board are operating (i.e. VCC for the board). This is 5V on the Iteaduino Leonardo. Input and Output Each of the 20 digital i/o pins on the Uno can be used as an input or output using pin Mode digital Write and digital Read functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition some pins have specialized functions: Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data using the ATmega32U4 hardware serial capability. Note that on the Leonardo the Serial class refers to USB (CDC) communication; for TTL serial on pins 0 and 1 use the Serial 1 class. TWI: 2 (SDA) and 3 (SCL). Support TWI communication using the Wire library. External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value a rising or falling edge or a change in value. See the attach Interrupt function for details. PWM: 3 5 6 9 10 11 and 13. Provide 8-bit PWM output with the analog Write function. SPI: on the ICSP header. These pins support SPI communication using the SPI library. 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. This means that if you have a shield that uses SPI but does NOT have a 6-pin ICSP connector that connects to the Leonardo's 6-pin ICSP header the shield will not work. LED13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value the LED is on when the pin is LOW it's off. Analog Inputs: A0-A5 A6 - A11 (on digital pins 4 6 8 9 10 and 12). The Leonardo has 12 analog inputs labeled A0 through A11 all of which can also be used as digital i/o. Pins A0-A5 appear in the same locations as on the Uno; inputs A6-A11 are on digital i/o pins 4 6 8 9 10 and 12 respectively. Each analog input provides 10 bits of resolution (i.e. 1024 different values). By default the analog inputs measure from ground to 5 volts though is it possible to change the upper end of their range using the AREF pin and the analog Reference function. There are a couple of other pins on the board: AREF. Reference voltage for the analog inputs. Used with analog Reference. Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board. Programming The Iteaduino Leonardo can be programmed with the Arduino software . Select Arduino Leonardo from the Tools > Board menu . The ATmega32U4 on the Iteaduino Leonardo comes pre-burned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the AVR109 protocol. You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header.
