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.
The subject of the sale is the original product for Arduino, Botland isthe official distributor of this company.
Botland is an official distributor of the Arduino development platform in Poland. We offer a wide choice of boards, modules and accessories from this popular brand, along with tutorials and a knowledge base for users. All Arduino products presented here are original.
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. |
