ATmega32U4 Micro DELL Arduino
Series ATmega (AVR)
ATmega32U4 overview
Arduino Micro ATmega32U4 is essentially a shrunk-down (1.9″ × 0.7″) version of the Arduino Leonardo. It is a microcontroller board based on the ATmega32U4 running at 16 MHz with 24 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs). This board ships with the male header pins soldered in, as shown in the product picture.
