Olimex ENC28J60-H: Worlds smallest ENC28J60 ethernet controller development board



Microchip’s ENC28J60 is a 28-pin, 10BASE-T stand alone Ethernet Controller with on board MAC & PHY, 8 Kbytes of Buffer RAM and an SPI serial interface. With a small foot print package size the ENC28J60 minimizes complexity, board space and cost. Target applications include VoIP, Industrial Automation, Building Automation, Home Control, Security and Instrumentation.


  • ENC28J60 Ethernet controller in the world’s most compact header form
  • LAN connector with build in transformer
  • Two status LEDs on LAN connector
  • SPI interface takes only few pins to add Ethernet interface to your microcontroller project
  • 10 pin interface on 0.1" row pins header
  • PCB: FR-4, 1.5 mm (0,062"), green soldermask, white silkscreen component print
  • Dimensions: 30x24 mm (1.18 x 0.95")
  • Space between the pin rows: 20 mm (0.8")

Arduino Library

Just to have mentioned Adam Dunkels’ work of uIP (micro IP) - Wikipedia , here the Arduino version for the ENC28j60 integrating it: soft-MAC by uIP, but same commands as Ardu’s Wiznet 5100 (hard-MAC) lib:

This version covers more targets:
