Description:
The Microduino-ENC28J60 ethernet module uses MicroChip 's high performance single-chip SPI bus network interface chip which is an IEEE 802.3-compliant Ethernet controller integrated MAC and 10BASE-T PHY. It supports full and half-duplex mode.
This module easily stacks on top of a Microduino-Core or Core+ board giving it IEEE 802.3 networking capability.
Characteristics:
U-shaped 27pin Microduino standard interface, with Microduino-RJ45 conntector.
The ENC28J60 network chip has strong support within the Arduino community with Libraries and example sketches already in existence.
Specification:
ENC28J60 Ethernet chip, SSOP28 package
IEEE 802.3-compliant Ethernet controller integrated MAC and 10 BASE-T PHY
Support full-duplex and half-duplex mode
SPI interface, SPI clock can be up to 20MHZ, maximum speed up to 10Mb / s SPI interface
Single-supply operation: 3.3V
Murata ceramic crystal 25Mhz
Dimensions: Length Width 25.4mm X 27.94mm.
Microduino-ENC28J60 Interface:
VCC-> 3V3
GND-> GND
CS-> D8
SI-> D11
SO-> D12
SCK-> D13
INT-> D2 (optional, need to connect R3 (0-2K))
RST-> RST

This is an example of how to use the Hobby Components Microduino ENC28J60 Ethernet
module (HCMIDU0005).
To use this sketch you will need to download and install the EthernetCard library
available at the following location:
https://github.com/jcw/ethercard
Alternatively, a known working snapshot can be downloaded from the microduino section
of our support forum:
http://forum.hobbycomponents.com/
This example program will serve a basic webpage at the ip address specified below.
As an example of content, the webpage contains the current status of the analogue input
pins.
