Description: The smallest, most powerful, and most versatile GPS receiver we carry just got more powerful.The Venus638FLPx is the successor to the Venus634LPx and has improved sensitivity and a faster update rate. The new module can be configured to an amazingly powerful 20Hz update rate. With two serial ports, UART and SPI interfaces (please see the datasheets on how to implement the SPI interface), 29mA 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 Venus638FLPx 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. The Venus638FLPx also allows for limited on-chip logging (check out the firmware below) In addition, the module supports data logging with an external SPI Flash!

The logger's SPI Flash can be configured over the TX and RX pins using our USB to Serial FT232 Breakout Board.
