ClearConnex engineering team has designed expansion boards for the Fastrack Supreme and Fastrack Xtend so that we can deliver the functionality of a custom built solution, with the cost-effectiveness of an off-the-shelf modem. The Sierra Wireless Fastrack is an off-the-shelf cellular modem which includes an open expansion slot that accepts off-the-shelf or custom cards within the self contained enclosure. Our ClearComm software platform also supports the features of the GPS Plus Card.
Feature Overview
The GPS Plus Card is available in different configurations. The Micro SD card and F-RAM options are mutually exclusive. The Card can be built with either one feature or with all features populated (except for Micro SD card or F-RAM)
- SiRFstar III-based GPS, MMCX antenna connector
- PIC microprocessor provides additionalprocessing power
- 26 GPIOs
- Micro SD card holder
- Ferromagnetic NVRAM
- USB Port (for Fastrack Supreme only)
All features are connected to the Fastracks OpenAT based cellular modem via the IESM connector. Software support for all features is available when ClearComm is loaded on the Fastrack.
