An interesting use of our EtherMega board has been demonstrated by Freetronics forum member Bernd Felsche, who has documented his networked cash drawer controller system. As part of a greater point-of-sale system, the EtherMega is used as a device to interface between the LAN and the cash drawers - and includes a good user interface for drawer setup via the network and some interesting use of EEPROM to store various settings and parameters.
As shown in the project above, Bernd uses the Freetronics EtherMega:
Quite simply the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
