INTRODUCTION
MOD-ENC28J60 is development board with UEXT connector and 10 Mbit
ENC28J60 ethernet controller from Microchip Technology Inc.
BOARD FEATURES
– MOD-ENC28J60 is the easiest way to add 10 Mbit ethernet connectivity to any
of our boards with UEXT connector
– ENC28J60 Ethernet controller with UEXT connector for easy connection to our
other development boards with UEXT connector
– LAN connecttor with build in transformer
– two status LEDs on LAN connector
– SPI interface takes only few pins to add Ethernet interface to your
microcontroller project
– UEXT 10 pin interface on 0.1" row pins header
– backward compatibility with ENC28J60-H with 2 x 5 pin header
– PCB: FR-4, 1.5 mm (0,062"), green soldermask, white silkscreen component print
– Dimensions: 40x24 mm (1.55 x 0.95")
– space between the pin rows: 20 mm (0.8")
ELECTROSTATIC WARNING
The MOD-ENC28J60 board is shipped in protective anti-static packaging. The board
must not be subject to high electrostatic potentials. General practice for working
with static sensitive devices should be applied when working with this board.
