The Leonardo differs from other Arduino\nboards using separate USB-Serial chip in that the ATmega32u4 has built-in USB\ncommunication, eliminating the need for a secondary processor. The Leonardo is\na great because you can use it to emulate a keyboard\/mouse\/joystick, which is\nhandy for many projects. Read more Power Supply: The board has 20 digital\ninput\/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a\n16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP\nheader, and a reset button. The keyestudio Leonardo can be powered via the\nmicro USB connection, or via an external power supply jack (DC 7-12V) or even\nwith female headers Vin \/GND (DC 7-12V). Memory Store: The Atmega32u4 of\nKEYESTUDIO Leonardo R3 Board has 32KB of flash memory for storing code (of\nwhich 4 KB is used for the bootloader), 2.5KB of SRAM and 1KB of EEPROM (which\ncan be read and written with the Eeprom library). Board Model: Neat little\nLeonardo r3 board works just like the original! Another great Arduino\nalternative. It works fine and the quality is good. The yellow and black theme\nis unique.
