BUILT-IN 2.4GHZ DR16 RECEIVER

 

The A2 has a built-in 2.4Ghz Radio technology DESST receiver system (the newest DJI Enhanced Spread Spectrum Technology), which supports the Futaba FASST series of transmitters. It can support 16 channels. Futaba transmitter users can use the system without any external receiver, which has greatly simplified the complexity of the system and improved the security of the remote control system.

---

SUPPORT FOR EXTERNAL RECEIVERS

 

A2 system has two reserved JR and SPEKTRUM satellite receiver ports, which support JR and SPEKTRUM satellite receivers. It currently supports SPEKTRUM DX6I, DX8 transmitters, other JR or SPEKTRUM series will be supported in the future.

The system supports external receivers including the Futaba S-Bus receiver, PPM receiver.

---

 

SUPPORT DJI D-BUS ADAPTER

 

The DJI D-BUS ADAPTER module (optional) can provide eight-way input or output. A traditional receiver can be used through this module, or can be used to extend the output ports. Please refer to the A2 user manual D-BUS ADAPTER section for more specific details of functionality.

---

 

DUAL CAN-BUS SYSTEM

 

The A2 system has a dual CAN-Bus design, which means that the system data throughput will be doubled and the extendibility is improved. At the same time, the important data and the non-critical data are assigned respectively on different CAN-Bus ports, which greatly improves the system stability.

---

MORE OUTPUT INTERFACES

The A2 is equipped with a minimum of twelve output channels, users can easily use it to control an Oct-rotor, and the other four channels can be used as a general output interface, for example, to control the DJI retractable landing gear on S800 EVO, to control Gimbal or camera switch, etc.

PRECISE POSITION HOLD AND WIND RESISTANCE

With the new generation GPS Pro/CompassModule and the hardware upgraded IMU module, the A2 has an optimized inertial navigation algorithm, which ensures the system can get a more reliable and accurate position and attitude estimate. The aircraft which is equipped with A2 will have very good performance in position hold even in a semi-closed environment, such as between buildings, it also has excellent hovering performance. At the same time, with the optimized algorithm of inertial navigation and the algorithm of wind resistance, the Wind Resistance performance of A2 is also improved, and the multi-rotor can have position and altitude locked accurately even in windy conditions.

INTELLIGENT ORIENTATION CONTROL (IOC)

Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using Intelligent Orientation Control (IOC), wherever the nose points, the forward direction has nothing to do with nose direction:

In course lock flying, the forward direction is the same as a recorded nose direction. See the following figures (Mode 2):

In home lock flying, the forward direction is the same as the direction from home point to the multi-rotor. See the following figures (Mode 2):
