Leonardo R3 ATmega32U4 Development Board With USB Cable Geekcreit for Arduino - products that work with official Arduino

Description Compared to other versions of the using a separate USB Serial converter chip the Leonardo innovatively uses a single chip solution Only with a Atmega32u4 USB communication and control 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 It also has other implications for the behavior of the board Greatly improve the applications Leonardo need the new version above IDE1 01 Specification Microcontroller ATmega32u4Operating voltage 5VInput voltage recommended 7V 12VInput voltage limits 6V 20VDigital I O pins 20PWM channels 7Analog input channels 12DC current per I O pin 40mADC current for 3 3V pin 50mAFlash memory 32KB ATmega32u4 of which 4KB used by bootloaderSRAM 2 5KB ATmega32u4 EEPROM 1KB ATmega32u4 Clock speed 16MHzPackage included 1 x compatible Leonardo R31 x USB cable
