Ethernut - embedded server on AVR
Ethernut is an Open Source Hardware and Software Project for building tiny Embedded Ethernet Devices.
Ethernut is an Open Source Hardware and Software Project for building tiny Embedded Ethernet Devices. It contains an AVR microcontroller (or the ARM9-based one) and Ethernet interface. You can use its own OS (Nut/OS) and build simple internet server with this board.
There are 6 modifications (named Ethernut1 - Ethernut 5 and EIR, which stands for Elektor Internet Radio). The cheapest (Ethernut 1) contains ATmega128, with on-chip 128 kBytes of Flash and an external 32 kByte SRAM. The 10 MBit Ethernet interface is based on the RTL8019AS.
The latest member of the Ethernut Family (Ethernut 5) provides an ARM9 CPU with integrated Ethernet MAC, 128 MBytes SDRAM, 1 GByte NAND Flash, USB Host and Device Interface, MMC/SD-Card Socket, CCD Camera Connector and very flexible power management. This board is also able to run Linux.
PS: I'm sorry for that, but the motto of that web: "When I was your age, we had 8 bit CPUs! And we liked it! And we didn't complain!" is simply brilliant! :)
