The "Ethernut" Ethernet starter kit is your best choice for hassle-free access to embedded Ethernet technology. The
kit features a small and inexpensive Ethernet Module that allows you to
easily add 10/100BaseT network capability to your applications. The
hardware and the preloaded OS and TCP/IP stack are open source and may
be used within non-commercial and commercial, open- and closed-source
projects without fee or royalties. Version 3.1 is the first
Ethernut board with an ARM7 CPU, which offers at least 10 times the
performance of its predecessors. The on-board memory of 256 kByte RAM, 4
MByte NOR FLASH and 4MByte serial DataFlash are expandable via the MMC
socket. Additional features are 100 MBit Ethernet, RS232 with full modem
handshake, realtime clock with capacitor backup and a flexible power
supply with two switching regulators. ARM7 Ethernet Starter Kit Features - AT91R40008 ARM7TDMI CPU running at 73.728 MHz
- 256 kByte RAM with 32-bit Data Path
- 4 MByte NOR Flash Memory with four Boot Options
- 4 MByte serial DataFlash Memory
- Solderpads for Configuration EEPROM
- CPLD with 144 Macrocells
- Programmable Clock Generator
- Real-Time Clock with SuperCap Backup
- 10/100 MBit Ethernet Interface
- Unique MAC address
- RS232 Interface with Full Modem Handshake
- Multimedia/SD Card Socket
- FFC Connector for optional LCD/Keyboard Panel
- Ethernut 1/2 compatible Expansion Port (3.3V only)
- Switching Voltage Regulator for 9-25V Input
Note:
The Ethernut 3.1 kit includes a JTAG adapter for programming the AT91
CPU on the board. The adapter plugs into a PC's USB port or DB9 PC
serial port. Use of your own ARM JTAG device is possible, but you would
have to build a custom cable as the Ethernut 3.0 board has a unique
10-pin JTAG interface.  Ethernut Software
The well documented software is an Open-Source implementation of a Real
Time Operating System called Nut/OS, and a TCP/IP protocol suite named
Nut/Net. Several application examples are provided,
including an embedded Webserver, a simple RS232-to-TCP/IP gateway, and
an Internet Radio playing MP3 streams. Ethernut Application Development
A well documented API and plenty of free program space and free data
memory are available to implement custom applications easily. The source
code is written almost entirely in C and included on CD-ROM. The
software license allows its royalty-free use in Open- and Closed-Source
Projects. ARM7 Ethernet Starter Kit Contents - Ethernut board version 3.1, preloaded with Nut/OS and Nut/Net TCP/IP stack
- Turtelizer 2 JTAG programmer for connection to PC USB or serial port
- RS232 serial cable
- Printed User Manual
- CD-ROM with complete source code and binaries, technical manuals and GNU tool chain for Windows and Linux
- IEEE registered individual MAC address
In addition you will need (not included): - Power Supply: 5-24V DC, 300mA
- RJ45 twisted pair Ethernet cable to connect the Ethernut board to your network
- Pentium class PC running Windows or Linux O/S
- USB cable if your PC doesn't have a DB9 RS232 port
