Apraksts
Plate LEONARDO R3
Leonardo mikrokontroliera plate bāzēta uz ATmega32u4. Tai ir 20 digitālie ieejas/izejas pini (no kuriem 7 var lietot kā PWM izejas un 12 kā analogās ieejas), 16 MHz kristāla oscilators, Micro USB savienojums, strāvas kontaktligzda, ICSP hederis un Reset poga.
Leonardo atšķiras no citām platēm ar to, ka ATmega32u4 ir iebūvēta USB komunikācija un tam nav vajadzīgs vēl viens procesors. Tas ļauj Leonardo parādīties datorā kā pievienotai pelei vai klaviatūrai papildus virtuālajam (CDC) seriālajam / COM portam.

Board LEONARDO R3
The Arduino Leonardo is a microcontroller board based on the ATmega32u4. 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, a power jack, an ICSP header, and a reset button.
The 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.
