DJI A2 Flight Controller
DJI A2 is the flagship flight controller of the DJI lineup. Supporting 9 motor mixes from quad to x-8 to octocopter, the A2 makes precision flight easy. The main controller (MC) is coupled with a GPS, IMU, PMU and LED to gather information and produce stable flight. Main Controller: This is the flight computer that takes pilot input along with gps data and creates stable flight commands to the motors. The A2 has an integrated 2.4Gz receiver which is compatible with the Futaba FASST and DJI DESST transmitter systems. There is a CANbus connection for up to 12 channels of output. IMU: Inertial Measurement Unit contains the gyros and other sensors to feed information about flight conditions to the MC GPS: Aids the MC in maintaining altitude, position, return to home, and hover commands. PMU: Power Management Unit managed the power from your batteries, and can be set up t monitor voltage and tell the MC to return enact a failsafe if voltage drops too low. LED: Provides visual indication on what mode the flight controller is in, how many GPS satellites are connected, and failsafe status. This LED also has integrated Bluetooth which accepts commands from a ground station to fly autonomous flights. Some of the integrated features of the DJI A2 include: Intelligent orientation control IOC, movement of the multicopter is in relation to the pilot, no matter which way the aircraft is pointing. Pushing forward will go way from the pilot and pushing left will make it fly left. Its just that easy. Point of Interest POI mode: After a POI is found, a button of the controller tells the MC to record that GPS location in memory, then when commanded by the pilot the multirotor will fly a circle with the nose pointed toward the object. Perfect for a video flyby of a stationary object with the flying camera. Intelligent Landing gear will automatically lower the landing gear in an emergency landing scenario to add some protection for your gimbal. Return to Home failsafe will return the drone to its point of takeoff if the transmitter link is broken. The pilot can also send a command to have the drone return to home automatically and land instead of flying it back, very useful in the event of a loss of visual contact. One motor fail protection, it happens in aerospace, it will happen on a hobbyist machine, with this protection the drone is still flyable enough to return to home, or at least land without destroying your precious equipment. Safety first.
