The smallest Computer in the World

Posted: November, 16 2007

Only slightly larger than an RJ45 connector (35mm×19mm×19mm), the picotux 100 is the world’s smallest Linux computer.

Inside, there is an ARM7 CPU at 55 MHz running uClinux kernel 2.4.27 and Busybox 1.0. Two communication interfaces are provided, 10/100 Mbit half/full duplex Ethernet and a serial port with up to 230.400 baud. Five additional lines can be used for either general input/output or serial handshaking.
