APM V2.8 Flight controller Description:
- 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 externalcompass.
- 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 down. The new version adopts US LP2985-3.3, 16V withstand voltage, more reliable, reducing the possibility of Bad Gyro health

Note:
1.About the APM 2.8 FC Board, because of the different production batches, the board colour or shell has a little difference, send it at random.
2. The firmware of GPS is fixed , do not need to revise it; You can use it directly after receiving the GPS
3. About the 8N GPS, Because of different production batch, there are two kinds of shell, send the shell at random.
