Description
Versatile GPS receiver based on Venus638FLPx (Venus634LPx successor). Compared to its predecessor, the manufacturer increased sensitivity and applied faster refreshing - up to 20 Hz. The module uses NMEA-0183 or SkyTraq standard.It communicateswith main circuit (e.g. any microcontrollerorArduinoorRaspberryPiset)via standardserialinterface(RX, TX outputs) with default transmission speed 9600 bps (adjustable to 115200bps).
This version has a SMA connector to connectan external antenna, connectors for data transmission, external flash memory (via SPI interface) and jumpers to configure the module: power consumption, memory selection and emergency power supply. Venus638FLPx requires a stabilized supply voltage of 3.3 V, it consumes 90 mA in full power mode and 60 mA in power reduction mode.
There is also a connector on the board to connect a battery or external super capacitor (0.2 F). Thanks to the emergency power supply, the receiver can be kept in hot-startable mode (quick start, standby) for even several hours without the main power supply.
