Functional Features
Weight Size
reduced by reduced by
Ultra-Light, Ultra-Compact, Ultra-Powerful
Through multiple design iterations, the AFC-A6 series flight controller has been reduced to a compact size of 55 x 38.8 x 14 mm with a weight of only 36g, significantly lowering overall system size and weight.
Compared with the AFC-A6S, the AFC-A6 is 61% lighter and 53% smaller, while still delivering powerful performance and abundant interfaces.
BalancedGyro™ Technology
Lower Noise · Higher Vibration Resistance
Sensors are the core of any flight controller. The AFC-A6 series adopts aviation-grade ICM45686 gyroscopes and accelerometers, featuring the world’s first BalancedGyro™ technology. This technology provides exceptional vibration resistance, superior temperature stability, and reduced inter-sensor coupling. Gyroscope noise as low as 3.8 mdps/rtHz, Accelerometer noise as low as 70μg/rtHz
STM32H7 Processor
Higher Clock Speed, More Possibilities
Powered by the high-performance STM32H743 processor running at up to 400 MHz, with 2 MB Flash and 1 MB RAM, the AFC-A6 series achieves lower CPU load and supports advanced features such as FFT filtering, temperature learning, and GPS-denied navigation, fully enabling ArduPilot and PX4 capabilities. The larger Flash capacity also provides ample space for LUA scripting and custom development.
IMU Temperature Compensation System
Reduced Sensor Drift
The AFC-A6+ is equipped with an IMU temperature compensation system, which actively heats the sensors to 45°C by default, maintaining them at the optimal operating temperature. This effectively reduces sensor temperature drift, improves low-temperature performance, and enhances overall system reliability.
IMU
Vibration damping
foam
Compact Design with Built-in Vibration Dampening
Despite its small size, the AFC-A6+ does not compromise on vibration isolation. Its IMU adopts a separated design, connected to the main board via a flexible flat cable. Combined with carefully selected custom damping foam, this structure effectively filters high-frequency vibrations, reduces gyroscope noise, and improves flight stability.
Multi-Sensor Redundancy Architecture
Enhanced Flight Safety
Designed for maximum precision and safety, the AFC-A6+ features a dual IMU redundancy architecture, utilizing two sets of high-vibration-resistance, low-drift, wide-range ICM45686 gyroscopes.
Additionally, it is equipped with dual ICP20100 high-precision barometers, providing multiple layers of protection for reliable flight control.
100 Mbps Ethernet Interface
Unlock Advanced UAV Capabilities
The AFC-A6 series integrates a 100 Mbps Ethernet interface, enabling direct connection to Raspberry Pi, NVIDIA Jetson platforms, mission payloads, and other computing modules. This allows advanced applications such as SLAM mapping, visual tracking, fiber-optic inertial navigation, and more—unlocking greater possibilities for UAV systems.
20 × 20 mm Mounting Pattern
Lightweight and Easy Installation
For user convenience, the AFC-A6 series includes standard 20 × 20 mm M2 mounting holes on the rear side, with a thread depth of 3 mm, making installation inside airframes simple and secure.
