- Arduino nano (another arduino can be used, like UNO, mini, etc)
- SSD1306 SPI oled display (7 pins)
- ENC28j60 ethernet breakout board
- Push button for reset (optional, nano reset can be used)
- Ethercard - https://github.com/njh/EtherCard
- SSD1306Ascii - https://github.com/greiman/SSD1306Ascii
Thanks to Bill Greiman for SSD1306Ascii library. Normal SSD1306 library provided by adafruit cannot be used with Ethercard since arduino memory restrictions
