More info

Pololu 3113 - A-Star 32u4 board version without microSD card support and without display; it has soldered connectors.

Description

Pololu A-Star 32U4 Prime is a board with Atmel ATmega32U4 microcontroller from the AVR family compatible with the size and arrangement of connectors with the popular Arduino Uno R3 and Leonardo , which allows attaching a wide range of Arduino shields. The user has access to all 26 GPIO microcontroller lines, 7 of them can be used as PWM, 12 can be used as analog inputs. ATmega32U4 is equipped with a full-speed USB interface, which is a big advantage over similar boards with USB <-> Serial converters. In addition to the standard CDC mode, the board can act as a USB HID device (as a mouse or keyboard). The USB connector is a micro-USB type.

The tile is available in two versions:

  • SV - with green PCB, can be supplied with voltage from 5..36 volts
  • LV - with blue PCB, can be supplied with voltage in the range 2.7.11.8 V.

This product requires an additional micro USB cable (not included!) To connect the device to the computer.

Compatibility with Arduino

A-Star 32U4 Prime is pre-programmed with an Arduino-compatible bootloader, bootloader takes 4 KB of Flash memory, 28kB is used for user's applications. The manufacturer provides a plugin for integration with IDE Arduino and a library that allows you to take full advantage of the A-Star capabilities. The A-Star 32U4 is equipped with the same microcontroller that Arduino Leonardo has , so most applications for Leonardo can run on A-Star 32U4.
