Mini GPS Module ATGM336H + Antenna

The ATGM336H GPS module is a tiny (13mm x 16mm) constellation positioning and navigation device that is capable of connecting with up to six satellites to approximation its geolocation on earth. The ATGM336H is a great low-profile alternative to the similar NEO-6M GPS module that is commonly used in the Arduino/Raspberry Pi sphere. The ATGM336H has an accuracy of 2.5m and is capable of updating its coordinates 1-10 times per second. The GPS module uses a serial protocol to communicate with the Arduino platform (similar to the NEO-6M). Many of the libraries that work with other GPS modules also work with the ATGM336H, making it a great replacement for projects that require smaller geometries or weigh very little.

Output Protocol

The ATGM336H series module uses the UART as the main output channel and outputs it according to the protocol format of NMEA0183. For details, please refer to "CASIC Multimode Satellite Navigation Receiver Protocol Specification".
