The Matchbox Webserver is based on a tiny single-board computer with a 66 MHz AMD 486DX CPU, 16 MB RAM, and 16 MB flash ROM — big enough to hold a useful amount of RedHat 5.2 Linux including the HTTP daemon that runs the project’s web server. At relatively low usage levels it consumes 800 milliwatts from a 5V power supply, rising to 2 watts at 100% CPU usage. It communicates with the outside world via two serial ports, a printer port, and a connector for a floppy drive. It measures 2.8″ x 1.8″ for an area of 5 square inches. Being 0.2″ thick this makes the volume one cubic inch (16 cc’s). It weighs 3/4 oz (20 grams).
