Programmable 2.4GHz Radio Base Station with AVR ATmega128.

iDwaRF-BOX V1.2 Radio Base Station

Description

The iDwaRF-Box expands the iDwaRF family by a powerful Hub module for wireless sensor networks with many sensors (255 sensors with the current iDwaRF-Net firmware version). The module is based on the same radio chip like the iDwaRF-168 module and provides an ATmega128 processor with 128kB flash and external 32kB SRAM memory, as well as a USB interface and a connector for an external antenna. See Infosheet for details.

Configuration:

The iDwaRF-Box provides an ATmega128 processor with 32k external SRAM, voltage regulator, USB interface, radio chip with external antenna connector (SMA), sd-card header (e.g. for wireless data logger applications), two push buttons and one LED. Optionally a Lantronix XPort can be mounted for simple ethernet connectivity.

You can find further information in the Infosheet.

Scope of Delivery

The iDwaRF-Box comes as fully SMD assembled module. The required leaded components (connectors, buttons, etc., except XPort!) are included as components kit and can be re-assembled upon demand.

Firmware:

Die frei verfügbare iDwaRF-Net Firmware bietet die komplette Funktionalität für ein drahtloses, sternförmiges N:1 Sensornetzwerk. Das Protokoll ist komplett gekapselt, die �bertragung von Daten erfolgt zwischen Host (z.B. PC) und iDwaRF Hub über ein einfaches serielles ASCII Protokoll. In den iDwaRF Sensoren können User-Funktionen eingebunden werden und der Datenaustausch erfolgt hier über einfache Datenfelder. Verschiedene Beispielapplikationen, z.B. für die onboard Komponenten des iDwaRF-NodeBoards oder ein drahtloser Chat via Terminalprogramm, können leicht an eigene Anwendungen angepasst werden.

Zubehör

For operating the iDwaRF-Box an external antenna (see below) is required, which has to be ordered separately. For PC connectivity a USB A-B cable is required, or an RJ45 ethernet cable for Ethernet operation. For programming the iDwaRF-BOX an ISP adapter with low-voltage target support is required.
