Ethernet network module ENC28J60 mini

Description

A module that enables the connection of the microcontrollers and development kits, including the Arduino, with the Ethernet network. The communication interface is the popular, digital SPI bus. On the board is Ethernet RJ-45  slot for the network cable and goldpin pins for connection to the main board. The supply voltage of the system is 3.3 V and the dimensions of the whole are: 51 x 19 x 16mm.

 

Available is alibrary for the Arduinomodule, along witha user manual for connection.

 

  Specification

• Supply voltage: 3.3 V

Name

Description

VCC

Supply voltage is 3.3 V.

GND

The potential ground of the system.

RESET

The reset of the system is activated with the low status. By default, it is in the high status - internally pulled up to VCC (pull-up). The pin tolerates the voltage of 5V.

CS

Chip select - selects a device of the SPI bus. It is activated with the low status. By default it is in the high status - internally pulled up to VCC (pull-up). The pin tolerates the voltage of 5V.

SCK

The clock input of the SPI bus. Pin tolerates the voltage of 5V.

SI

Line of the input data of the SPI bus. Pin tolerates the voltage of 5V.

SO

Line of the output data of the SPI bus. Pin tolerates the voltage of 5V.

CLKOUT

Programmable output clock line.

WOL

Must be left not connected

INT

Internal interrupt output .
