Product description

The ethernet module of myAVR is an extrem compact network solution. With it you can realise an embedded web server. The module has an own Mac address and can be used as an interface between a microcontroller and the network or it can handle measurement and control tasks. It's addressable in the network via the IP address.

On the myEthernet you can save and load websites and user interfaces respectively. A remote maintenance of the system is also possible (e.g. via a web interface), as the module and its integrated microcontroller can communicate over the network or over the internet with any PC which has an ethernet connection. This is possible because of the integrated microSD card slot. The microSD card slot is compatible with cards in a FAT file system with size up to 2 GB. This allows the upload of large html sites, log files and graphics that can be implemented in an embedded web server. Interfaces are a 10-pole ISP port, an interface for a myAVR Board as well as an interface to other myAVR add-ons beside the ethernet port. The scope of supply contais a female connector and a multi-pin connector for a better connection. Because of that you can use it as an add-on to the myAVR Boards or separately. The power supply is provided by the 20-pole multi-pin connector for the myAVR Board or via the 10-pole ISP interface.
