Arduino Leonardo - based controller ATmega32u4. The platform has 20 digital input / outputs, 16 MHz crystal oscillator, connector micro-USB, power jack, ICSP and reset button. To work you need to connect to a computer via the platform cable USB, or energize using the AC / DC adapter or battery.

Power

Arduino Leonardo can be powered via USB or an external power supply.

The platform can work with external power supply from 6 V to 20 V. The recommended range is 7 to 12 V.

memory

The microcontroller ATmega32u4 has 32 KB of flash memory, of which 4 KB used for the bootloader, and 2.5 kB RAM (SRAM) and 1 KB EEPROM. (which is read and written using the library EEPROM).

Connection

On the platform Arduino Leonardo can communicate with a computer, another Arduino, or microcontrollers in several ways. ATmega32U4 support serial UART TTL (5V), digital pins 0 (RX) and 1 (TX). ATmega32U4 can also organize a series connection with the programs on the side of your computer via USB, so that they "talk" to the board via a virtual COM port.

programming

The platform is programmed by software Arduino. From the menu Tools> Board selected «Arduino Leonardo» (according to the established microcontroller). Detailed information can be found in the reference and tutorials.

Current protection connector USB

In the Arduino Leonardo samovostanavlivayuschiysya integrated fuse (automatic), which protects the computer's USB port short circuit and overcurrent. Srabatyvat fuse when the current more than 500mA from the USB port and opens the circuit as long as the normal currents will not be impeccably renovated.

Physical characteristics

The size of the printed circuit board Leonardo constitute 6.9 to 5.3 cm. The USB connector and power connector extend beyond the data size. Four holes in the board allow to fix it on the surface. The distance between the digital outputs 7 and 8 is equal to 0.4 cm, although among other conclusions, it is 0.25 cm.
