You can find detailed pin description in the Charon 2 - module datasheet, include combined functions etc..
Detailed electrical paramethers (pin driver description etc..) you can find in the Atmel's ATmega128 MCU datasheet.
You can choose separated transformer as “DIL14” size component (YCL 20F001N or Bothhand FS2022). If you need save PCB space, you can use transformer together with the RJ45 connector in one component (LF1S022).
Separated transformer is a little better suited for industrial applications due to increased insulation strength, thanks to the standard packaging of the magnetic.
You can find some transformer datasheets on the CD to the Charon 2 Development Kit. You can see separated GND and GNDA on this scheme.
The termination resistor 100W on the TPI pair, known from the Charon I module is already placed on the Charon 2 module.
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.
There is originaly loaded demo application in the Charon 2 modules. It's a simple demo how to work with all peripherals on the Charon 2 Development Kit board, but it's well documented in the manual = it can help you a lot in beginning.
A well documented Ethernut API and more than 100 kByte program space and 20 kByte data memory are available to easily implement custom applications. The source code is written almost only in C and available for download. The licence allows its use in Open and Closed Source Projects without paying royalities, even not in commercial applications. The developer can choose between two different development environments, the freely available GNU AVR Compiler Collection for Linux and Windows and the commercially supported ImageCraft AVR Compiler for Windows.
Internal and external RAM address spaces are wired identically on the Ethernut 1.3F board and Charon 2 module. But the ethernet controller driver Realtek 8019AS is mapped in the I/O devices address space (0x8000 – 0xFFFE) many times (8000h, 8100h, 8200h, 8300h, …. FE00h, FF00h), according to original Ethernut 1.3F board where the RTL8019AS is mapped on the on 8300h-831F address only and space 8320h-FFFF is free to other I/O devices.
On the Charon 2 module it isn't possible to map devices to the address space (address and data bus isn't available on the connectors), finally it's 100% SW compatible with the original Ethernut board software.

Development Kit contains full documented example on using all peripherals contained on Development Board (Digital Inputs/Outputs, 1-Wire thermometer, Serial port, LCD display, ..) using a simple WWW demo page.
Check the Charon 2 Development Kit manual
Hyperion Unit is a baseboard & metal enclosure for the Charon 2 module. Tou can use it free for your SW application based on Charon 2 modules.
Datasheet: Hyperion_Unit.pdf (baseboard scheme, enclosure dimnsions)
The following peripherals are used on the base board:

Question: Are there any restrictions copyright to the Charon 2 modules?
Answer:
No, original Ethernut is free, Charon 2 and it's SW is free too.. Only our commercial end user products are useing Charon 2 technology and they are copyrighted.
Question: Where I can buy Charon 2
DK?
Answer: You can buy it from us - check
the pricelist. You can contact Egnite company (authors of the original
Ethernut) in Germany or another our disributors...
Question: We want to control network device within our software. Do you have any SW examples, programming libraries or similar?
Answer:
Yes, there are some good examples demonstrating how to use our ethernet devices with Borland C++ and Delphi.
You can check some very easy communication examples using Visual Basic, JAVA and PHP. Check our Support & Download page.
We have a minimum of 20 pcs in stock at all times. It can be shipped via FedEx next day all over the world. We accept payement by Credit Cards or Wire Transfer, check our prices in the PriceList .
Or try to contact your nearest distributor of our products - International Distributors .
