The Ethernut V3.1 is a webserver 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 4MBytes 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.
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.
ARM7 Ethernet & Web Server Board 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 Data Flash Solder pads 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 board has a unique 10-pin JTAG interface, whereas most ARM JTAG Debuggers have a 20-pin connection. You will need to build your own cable if you want to debug using JTAG, or purchase the Starter Kit which includes a compatible debugger.
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.
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
