Description
It is a board based on the well-knownArduino Leonardomodule additionally equipped with Ethernet controller and microSD memory card reader. Thanks to this device, the user can easily connect the project to the Internet (IoT) without installing additionaloverlays, so called shields.Built-inmicroSD memory cardreader allows you to save files on an external data carrier. Support for the above mentioned peripherals is enabled by built-in libraries inArduino IDE environment: Ethernet and SDcard.
The subject of sale is original Arduino product, Botland is anofficial distributor of this company.
The board contains ATmega32u4 microcontroller equipped with 20 digital inputs/outputs, 7 of which can be used as PWM outputs (e.g. for controlling motors) and 12 as analogue inputs. The board is clocked with a 16 MHz clock signal, has 32 kB of Flash memory and 2.5 kB of SRAM memory.
| This version of Arduino Leonardo has Ethernet network controller - W5500 chip and microSD memory card reader. |
Main features
Below we present some features that distinguish Arduino modules from other programmable tiles.
| The name | Description |
|---|---|
|
Installed bootloader |
Thanks to the installed bootloader, the appropriatemicroUSB cable andsoftware from the manufactureris sufficient to program the device. |
|
Ethernet Micro SD |
This version has an Ethernet controller with RJ45 connector and a microSD memory card reader. |
|
Arduino Shield |
The layout of connectors enables installation of dedicatedArduino Shieldcovers. |
|
Extracts . digital |
20 digital inputs/outputs enable, among others, to control LEDs, relays and read button states. |
|
Performance Current |
The maximum current capacity of a single output is 40 mA. |
|
Outputs PWM |
7 PWM outputs allow e.g. for motor control and diode brightness adjustment. |
|
Inputs analogue |
The 12 inputs of the built-in 10-bit analogue-to-digital converter support, among others, sensors with analogue output. |
|
Communication serial |
The device supports popular communication interfaces, among others: UART, I2C and SPI and USB. |
| Special functions | Some pins have special functions, a brief description of which is available in our guide. |
|
Memory Embedded |
Atmega32u4 chip is clocked with 16 MHz signal, has 32 kB of EEPROm Flash 1 KB and 2.5 kB of SRAM. |
|
Power supply DC connector |
Any power supplyfrom 7V to 12V with 5.5 x 2.1mm DC connector can be used to power Arduino. |
|
Power supply USB port |
You can power the board from your computer viathe microUSB cable,whilekeeping in mindthat the maximum current capacity of the USB port is 500 mA. Arduino has a system that protects the socket against short circuit and too high current flow. |
|
The connector . ICSP |
The module has ICSP outputs for connecting an externalAVR programmer. |
|
Pin IOREF |
The IOREF pin allows for direct access to the voltage with which the I/O outputs work. |
|
Built-in LED |
The connected LED on pin 13 allows debugging of simple programs. |
|
Output 3,3 V |
The built-in voltage regulator enables external devices to be supplied with 3.3 V with current consumption of up to 50 mA. |
|
First start-up In order to make it easier to start working with the module, we have prepared aguidethat covers the installation and first start-up of Arduino environment. |
