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

The advantage of module A-Star Mini SV, is the ability to power with a high voltage with a voltage from 5 V to 40 V.
