This is a compact GPS module made by open-smart and utilises the GT-U7 GPS receiver. The module also includes a USB serial interface which can be accessed via a micro USB connector or directly via its 0.1” pitch serial TTL header (supplied header pins requires soldering). Out of the box the module will automatically output GPS data in the standard NMEA format making it compatible with many types of hardware and software with no configuration required. The module is also supplied with a detachable antenna which connects to the module via a U.FL pigtail cable allowing the antenna to be located in the optimal position.
