LEONARDO R3 ATmega32u4 board + Arduino compatible USB cable

It has an Atmega32u4 chip running at 16Mhz with a factory-loaded bootloader.
The Leonardo module has all the connectors that the Arduino Leonardo R3 and is compatible with all Arduino shields. LEONARDO R3 ATmega32u4 board + Arduino compatible USB cable features:
- ATmega32u4 microcontroller,
- Operating voltage 5V,
- Power (recommended) 7-12V,
- Digital pins I / O 20 (of which 7 can be used as PWM outputs),
- Analog input pins 12,
- DC current through I / O Pin 40 mA,
- DC current for pin 3.3V 50 mA,
- Flash memory 32 KB (of which 4 KB are used by the bootloader),
- SRAM 2.5 KB,
- EEPROM 1 KB, - Clock speed 16 MHz,
- Interface: UART, USB, SPI, I2C,
- USB communication - Atmega32u4,
