Product description: Arduino Ethernet Rev 3
The module allows for easy connection to the Ethernet network. This version of Arduino is also equipped with MircoSD memory card reader, which allows you to store more data. The board containsATmega328microcontroller, equipped with14 digital inputs/outputs, of which 6 can be used as PWM outputs (e.g. to control motors) and 6 analog inputs. The board is clocked with a 16 MHz clock signal, has 32 kB of Flash memory and 2 kB of SRAM memory.
Arduino Ethernet does not have a system controlling USB interface. For programming you needUART USB adapter orprogrammer (e.g. USBasp).
|
In our offer you will also find ArduinoLeonardo Ethernet,which can be programmed directly via USB port. |
Main features of Arduino Ethernet
Below we present some features that distinguish Arduino modules from other programmable tiles.
| The name | Description |
|---|---|
|
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 |
14 digital inputs/outputs enable, among other things, to control LEDs, relays and read button statuses. |
|
Performance Current |
The maximum current capacity of a single output is 40 mA. |
|
Outputs PWM |
6 PWM outputs allow e.g. for motor control and diode brightness adjustment. |
|
Inputs analogue |
6 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. |
| Special functions | Some pins have special functions, a brief description of which is available in our guide. |
|
Memory Embedded |
Atmega328 chip is clocked with 16 MHz signal, has 32 kB of flash memory, 1 kB EEPROM and 2 kB 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 |
The board can be powered from a computer viaa USB cable witha maximum current capacity of 500 mA. Arduino has a system that protects the socket against short circuit and too high current flow. |
|
Connector . ICSP |
The module has ICSP outputs to connect 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. |

Aruino Ethernet programming
Creating and uploading software enablesfree environmentprovided by the manufacturer. Arduino Ethernet does not have a chip controlling USB interface. That's whyUART<->USB adapter orAVRprogrammeris required for programming.
