Ken Boak discussed the Nanode Arduino-based network node. The Nanode is an all through-hole network development board, designed specifically as a home monitoring and automation platform. Firmware built in the Arduino IDE using open source libraries reports statistics to Pachube, a website that shows real-time data from small internet devices.
The hardware combines an Arduino with an ENC28J60 ethernet chip, and it’s available for around $40. Way cheaper than an Arduino + ethernet shield. On the bottom of the PCB there’s a footprint for an optional 25AA256 32K serial SRAM, and the next version will add a footprint for an RF module too.
