This version eliminates the 1.0mm 6P SM06B GPS interface of V2.52 old version, and change it into DF13-4P I2C external compass interface.
Put DF13-5P GPS interface with external compass interface, convenient for the connection of GPS and external compass.
V2.52 I2C interface changes to multifunctional MUX interface
Modified version added isolation resistor, when the OSD interface used with telemetry, the interfaces is effectively avoided
V2.52 version 3.5V power supply adopts IPS79133, 6V withstand voltage, output current 100mA, need to supply power for six IC, slightly inadequate power supply ability, easy to be burnt downs. The new version adopts US LP2985-3.3, 16V withstand voltage, more reliable, reducing the possibility of Bad Gyro health
