Module embeds GPS and tri-band GSM/GPRS

Jan 18, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — 3 views

Eurotech SpA is shipping a 12-channel GPS and tri-band GSM/GPRS wireless module for PC/104-expandable embedded boards and systems. The COM-1289 complies with PC/104 dimensions and bus standards, and supports Linux, among other embedded OSes, according to the company.

The COM-1289's GPS function is based on a low power, high sensitivity Fastrax iTrax03 GPS receiver chipset that offers reliable positioning in difficult urban canyon and dense foliage environments, Eurotech says. Position can be updated at a 1Hz to 3Hz rate, and GPS data is available in NMEA or binary protocol.

The COM-1289's cellular communications function is based on an “internationally approved” Siemens MC55 tri-band (900/1800 and 1900MHz) GSM/GPRS wireless chipset said to support SMS, high-speed GPRS data, fax, and voice communication. The module provides an easy access onboard locking SIM-card slot, along with signals for connection of an external SIM card. An audio I/O-port can connect to other devices, or be used directly with a headset for voice communication.

The GPS and GSM/GPRS functions are accessed via standard UART interfaces, resulting in compatibility with virtually all operating systems, the company says, specifically citing Linux, Windows CE, and Windows XP Embedded.

In addition to GPS and GSM/GPRS, the COM-1289 module provides a pair of 16550-compatible RS232 serial ports for legacy communications purposes, Eurotech says.

The module is configured via software, with all functions settable while it is installed in a target system. This includes serial port base address, interrupts, GPS communication protocol, and so on. Configuration data is stored in a non-volatile EEPROM — no jumpers are used — resulting in enhanced mechanical reliability, the company notes.

The COM-1289 appears to be shipping immediately. Pricing was not disclosed.
