Programmable 2.4GHz Radio Board with AVR ATmega128, SRAM, USB (, Ethernet).
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.
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 Übertragung 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.
A suitable programming adapter for the iDwaRF-Box is the CrispAVR-USB.
