Ethernet PICtail™ Daughter Board Signal Interface Overview Function I/O Pin Description 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.

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 (see device data sheet DS39662 for additional information) • 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.

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.
