Universal GPS receiver based on the Venus638FLPx system (the successor Venus634LPx). Compared with the predecessor, the manufacturer has increased the sensitivity and applied a quick update - up to 20 Hz. The module uses the standard NMEA-0183 or SkyTraq. With the main system (e.g., any of a microcontroller or kit Arduino or Raspberry Pi) communicates through a standard serial interface (pins RX, TX) default transmission speed is 9600 bit / s (adjustable up to 115200 bps).


This version has a SMA connector for connecting external antenna, connectors for data transfer connect external Flash memory (SPI), as well as the jumpers for setting of unit: power consumption, memory select, and emergency power. Venus638FLPx requires a stabilized supply voltage of 3.3 V, consumes 90 mA in full power mode and 60 mA in the reduced power mode.


On Board there is also a connector for external battery or super capacitor (0.2 F). Through the use of emergency power supply the receiver can maintain in a mode of hot-startable (quick start, waiting), even for several hours without main power.
