Overview
The Ethernet PICtail™ Daughter Board is an Ethernet demonstration board for evaluating
Microchip Technology's ENC28J60 stand-alone 10 Base-T Ethernet controller. It is an expansion
board compatible with a number of PICDEM™ demonstration boards. A complete list of compatible
PICDEM demonstration boards is available on Microchip's web site.
Getting Started
To get started, a compatible PICDEM demonstration board is required. In general, a board is
compatible if it has a PICtail™ board interface expansion port, which is a 14x2 connector. Most
PICDEM demonstration boards do not have the female header installed. Thus, a 14x2 female
connector is included with this kit for the user to install onto the PICDEM demonstration board if
necessary. When connecting the two boards together, pay close attention to the orientation of the
connector and pin alignment. The AC/DC power adapter should be plugged into the PICtail board's
power socket. Only one AC/DC power adapter is required because the Ethernet PICtail board is
capable of supplying power to the PICDEM demonstration board.
Features
• ENC28J60 Ethernet Controller with 25 MHz oscillator and integrated magnetic RJ-45 connector
• 256 Kbits SPI EEPROM (25LC256) for storing web pages and configurations
• Dedicated power supply
• PICtail™ Daughter Board connection interface
Board Configurations
As shipped from the factory, some of the jumper locations are bridged by circuit traces forming a
default setup. To change this, the user will need to cut the traces and install pins and a block
jumper. Afterward, the features can be enabled or disabled easily by installing or removing the
jumper.
Firmware
Firmware examples can be downloaded from
sure to download the firmware version that has been designated for the particular PICDEM
demonstration board that you have.

Media Access Control (MAC) Address
For evaluation purposes, each Ethernet PICtail board comes with a board number which can be
used to form a unique MAC address. This number can be found on the sticker label on the back
of each board. To form a MAC address, replace the last 3 bytes of the following MAC address,
00-04-A3-XX-XX-XX, with the number from the sticker. The number on the sticker is in decimal
format and conversion to a hex number is required. For example, if the sticker has the value of
"12345", then the MAC address would be 00-04-A3-00-30-39.
