A-Star 32U4 Micro 5V/16MHz - Pololu 3101
The module is equipped with Atmega32u4 microcontroller with installed bootloader compatible with the environment of Arduino. It is equipped with 18 digital inputs/outputs, as well as the popular communication interfaces. It works with voltages of 5 V. The advantage of A-Star module is its small size - compatible with the housing of DIP20.

Description
A-Star, as well asthe Arduino Micro, is based on theLeonardo module - it uses the Atmega32u4 microcontroller from AVR family. Equipped with 18 digital inputs/outputs, 7 of which can be used as PWM outputs and 8 as analog inputs. The system works with voltages of 5 V, with clock signal with a frequency of 16 MHz. The advantage of the module is its small size - compatible with the case of DIP20.
Botland is an official distributor of Pololu electronics and robotics parts. Countless robots hold at least one component of this brand in their build. Our team guarantees that all Pololu products presented here are original.
Specification
- Supply voltage:
- From 5 V USB socket
- Outer VIN: 5 V to 15 V
- Microcontroller: ATmega32u416 MHz
- I/O pins: 15
- PWM channels: 7
- Built-in USB full-speed controller
- Number of analog inputs: 8
- Serial interfaces: UART, SPI, I2C
- External interrupts
- Two LEDs at the user's disposal
- Led out ICSP connector to connect an external AVR programmer
- MicroUSB connector for programming (microUSB cable not included)
- The module is compatible with Arduino IDE
- Set has goldpin connectors for self-soldering
- Dimensions: 27 x 15 x 4.7 mm - case of DIP20
- Weight: 1.5 g (without connectors)
Unlike theArduino Micro, it does not have soldered connectors (however, goldpin strips are included in the package). The user decides which leads will be needed so the board can maintain its small size.
Attention! Before connecting, readthe installation guide. |
Leads
The figure above shows the distribution of leads of the A-Star module from Pololu. With Yellow marked were I/O pins(input/output) with the name in accordance with the documentation of ATmega32u4, with green color marked were analog inputs of the A/C converter. On a gray background with the green font indicated were the names of the leads characteristic for the Arduino.
Power
The module can be powered with 5 Volts through a micro USB cable and the external device (5 V - 15 V), for example, the AC adapter, the battery or the rechargeable battery. If the supply voltage is higher than 5V, it should be connected to VIN lead, which is connected with a stabilizer.
Inputs/outputs
A-Star has 15 digital inputs/outputs (I/O). Each pin allows for current consumption with a maximum current of 25 mA, which allows for direct connection of LEDs with the resistors and controlling other chips. In addition to standard I/O, some of the leads also havespecial functions.
Programming
Creating and downloading software is allowed by the free environment of the Arduino IDE.Implemented bootloader allows you to send the program directly viathe micro USB cable. A detailed description can be found inthe instructionssupplied by Pololu.
