Description

A-Star Prime LV is a development kit compatible with Arduino Leonardo. The platform is based on the Atmega32U4 microcontroller, with 32 kB flash memory, 2.5 kB SRAM and 1kB EEPROM. The system used supports the USB interface, so you do not need a programmer to use the board. A-star is equipped with 26 ports, of which 7 ports support PWM modulation, and 12 are analog. There are as many as 43 GND pins on the board, which makes it easier to connect peripherals. The built-in step-up / step-down converter allows you to supply the system with a voltage from 2 V to 16 V. The PCB also has a buzzer and a connector to connect the LCD display with the HD44780 controller.
