DG440 Controller

Feature packed Eurocard micro Controller

The DG440 is a powerful micro controller on a Eurocard standard card. It incorporates five serial ports, temperature sensor, Real Time Clock and numerous other features on a small, low power board. It is ideally suited for small control applications, especially Home Automation applications, and applications requiring loads of serial communications.
