Arduino Leonardo - module A000057

Product description: Arduino Leonardo - module A000057

The Arduino Leonardo is one of the most popular versions of the series. The Board contains an ATmega32u4 microcontroller with the participation of 20 digital inputs/outputs, of which 7 can be used as PWM outputs (e.g. for motor control) and 12 as analog inputs. The system works with the signal ticking with the frequency of 16 MHz, has 32K Flash and 2.5 KB RAM SRAM.

Key features of Arduino Leonardo module

Below are a few features that distinguish modules Arduino compared to other programmable tiles.

 

Name Description

Installed

bootloader

Thanks to bootloader, the only necessity for unit programming, is the appropriatemicro usb cableandthe software from the manufacturer's website.

Arduino

Shield

The distribution of connectors allows for the installation of special plates, so-calledArduino Shield.

Digital outputs/inputs

20 digital inputs/outputs allows, in particular, control of LEDs, relays and reading the button states.

Efficiency

current

The maximum power load for a single output is 40 mA.

Output

PWM

7 PWM outputs, motor control and brightness control of the LEDs.

Analog inputs

12 inputs of built-in analog-digital converter with a resolution of 10-bit, support, in particular, sensors with analog output.

Serial communication

The device supports popular network interfaces, including UART, I2C and SPI, and USB. Special functions Some of the pins have special functions that a brief description is available inour guide.

Memory

built-in

The Atmega32u4 chip has the signal clock frequency of 16 MHz and has 32 KB Flash memory 1 KB EEPROM, 2.5 KB of RAM SRAM.

Power

DC connector

To power the Arduino, you can useany power sourcewith a voltage from 7 V to 12 V with DC connector 5.5 x 2.1 mm.

Power

USB port

The tile can be powered from a computer via amicroUSB cable, bearing in mind that the maximum power load for the USB port is 500 mA. Arduino has a system that protects the socket from short-circuit and the flow of too high current.

Connector

ICSP

The module has ICSP inputs/outputs for connecting an externalAVR programmer.

Pin

IOREF

The IOREF Pin provides direct access to the voltage with which work I/O.

Built-in

led

The connected led on pin 13, allows debugging simple programs.

Output

3.3 V

Built-in voltage regulator allowas powering external devices with the voltage of 3.3 V with current consumption of 50 mA.

 

First run

To help you get started with the module, we have prepareda tutorial that will help you with the installation and first run of the Arduino environment.
