Taking inspiration from the good folks at Nanode and an Instructable I saw recently, I`ve come up with another AVR based Ethernet board that can be programmed and used like an Arduino. It`s a simple design based on the ATMega and Microchip`s ENC28J60 Ethernet controller with SPI. Running MQTT on one of these will open up a few options for h

omeautomation and remote sensor monitoring. It`s not as complex as the Nanode. It doesn`t have the Arduino header locations, but all the major pins are available at headers. There is a 25L512 chip providing 512 Kbit Serial EEPROM for MAC addresses and logged data if one needs it. The PCB is only 80x50mm in size! The JeeNode is a wireless micro-controller board designed for a variety of Physical Computing tasks. From measuring and reporting temperature, humidity, and other environmental data to tracking and controlling energy consumption around the house. It was inspired by the Arduino Duemilanove and Uno boards, and by the Real Bare Bones Board  (RBBB) from Modern Device.
