The LOCOSYS LC20031-V2 integrates a global navigation satellite system (GNSS) receiver with an embedded antenna to create a complete GNSS module that can track up to 135 signals at a time from GPS and many other satellite systems, with support for both L1 and L5 bands. It can provide updates at up to 10 Hz, has a built-in rechargeable battery for rapid satellite acquisition (external power is still required for normal operation), and outputs data as NMEA sentences through a 3.3 V or 5 V TTL-level serial port.
