Description of product: Pololu A-Star 32U4 Mini SV - Atmega32u4

A-Star, as well as the Arduino Micro, based on the Leonardo uses the Atmega32u4 microcontroller from AVR family. Equipped with 26 digital inputs/outputs, of which 7 can be used as PWM outputs and 12 as analog inputs. The system works with voltages of 5 V, a frequency of an external signal with a frequency of 16 MHz.

The advantage of module A-Star Mini SV is the ability to supply a high voltage from 5 V to 36 V.
