The U-BLOX NEO-6M Mini GPS Module for Multirotors has no onboard compass. It offers a great option for RC multicopters since the compass of multicopters should be placed as far from power and motor sources as possible to avoid magnetic interference. Built-in antenna ensures its high performance in signal receiving and sending. Even better、 EEPROM saves all your configuration data. Powered by inbuilt MS621TF battery、 it has low power consumption and long battery life.
