A2 A New Standard in Flight Control 

DJI A2 multi-rotor stabilization controller is a complete flight control system for various multi-rotor platforms, for 

commercial and industrial AP applications. It opens an unprecedented era of precise positioning and perfect 

flight control in harsh environments for flight control systems.

Its high performance antenna, low noise anti-interference front-end RF design, accurate position and speed 

calculating, represent comprehensive technological breakthroughs. These combined features make the 

positioning performance of the GPS Pro near perfection; With higher accuracy performance, larger measuring 

range, and a unique damping design and calibration algorithm, the IMU is able to provide stable output even in 

high vibration and large movement environments. The built-in receiver system directly supports the popular 

transmitters, and it also supports a variety of external receivers. Combined with abundant output interfaces and 

flexible configuration, it makes the flight controller competent for complex control and airborne equipment 

operation; the new dual CAN-Bus design greatly improves the data throughput and stability of the system.

Based on the technology and design philosophy of DJI’s Ace series of high-performance controllers, the A2 

offers you a brand new flight experience. The A2 adopts a full metal case design and utilizes high quality 

components precisely calibrated with temperature compensation in all gyros and sensors, industry renowned 

flight algorithm in flight control and UAV field.

Features

GPS-Compass Pro Module

The GPS receiver of the A2 GPS-Compass Pro Module is equipped with a new high gain and high 

performance right-handed circular polarized (RHCP) antenna, the low noise anti-interference front-end RF 

design and the optimized localization algorithm, which provides the GPS Pro with stronger anti-interference 

performance, a stronger ability to capture satellite signals and a more accurate position hold calculating ability. 

All these features have enhanced its position locking capability.
High Sensitive Built-in Damper IMU Module

The interior sensor of the A2 IMU has been upgraded comprehensively, and with higher accuracy performance, 

larger measuring range, and a unique damping design and calibration algorithm, the IMU is able to provide 

stable output even with high vibration and a large movement environment. The advanced sensor temperature 

compensation algorithm and industrialized accurate calibration algorithm gives the IMU excellent performance. 

With the DJI innovative damping structure and material, it is unnecessary to install a framework or cushioning, 

you can simply stick it on the aircraft. Small size and weight allow easy installation in a tight space, it simplifies 

the installation process, for various aircraft sizes.

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.

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.
