Venus GPS Logger with SMA Connector

This is one of the smallest and most powerful GPS loggers on the market. The Venus GPS module can be configured to an amazingly powerful 10Hz update rate, with 14 channel tracking and can store up to 32Mbits of GPS data! Boosting 28mA operating current, and high sensitivity, this receiver seriously opens new doors for tracking. Module outputs the standard NMEA-0183 or SkyTraq Binary sentences at a default rate of 9600bps (adjustable to 115200bps).

The Venus634LPx has improved sensitivity, an integrated LNA (with multipath detection and suppression), built-in RTC, and integrated single power supply making it very simple to use. In addition, the module supports data logging with an external SPI Flash!

Note: VBat pin is permanently connected to 3.3V in the current version. Next revision will give you the option to select VBat open or 3.3V.
