Created for the assembly of dynamic racing and freestyle devices of small format flight controller HGLRC SPECTER 25A AIO. This is a high-performance All-In-One board. It combines a powerful flight controller and a 4-in-1 speed controller. This solution is ideal for 3-4 inch quadcopters. You get great performance in a compact form factor. Assembling the drone will become easier, and the electronics will be more reliable.

Flight controller HGLRC SPECTER 25A AIO - this is a serious component for serious projects. It's designed for pilots who want power without bulky stacks of boards. Integration of key systems reduces weight and complexity. This directly affects the maneuverability and cleanliness of the assembly. Your drone will become more responsive and predictable in flight. This is the choice for those who build winning cars.

Five main advantages of the device

• Powerful integration in AIO format. Combines a productive FC and a 4-in-1 ESC 25A. This eliminates unnecessary connections and reduces the weight of the structure.

• Sufficient power 25A per channel. Suitable for popular 1404-1507 motors on 3-4″ drones. Ensures stable operation under high load.

• High voltage support (up to 6S). Allows the use of high-energy 6S batteries. This gives maximum performance for small drones.

• Compact size 30×30 mm. Fits perfectly into most frames for 3-4″ devices. Leaves room for other components.

• Modern F7 processor and gyroscope. Provides ultra-fast data processing. This is critical for precise control at high speeds.

Operating principle and technical details

AIO flight controller is a single center for control and power electronics. It receives pilot commands from an external radio receiver (eg ExpressLRS). At the same time, a high-frequency gyroscope records the slightest movements of the drone. The powerful F7 processor processes this data thousands of times per second.

Based on complex calculations, the processor determines the necessary adjustments. It sends control signals to the built-in 4-in-1 speed controller. This regulator accurately doses the current for each motor. HGLRC SPECTER 25A AIO makes this cycle incredibly fast. The result is lightning-fast response and absolute control in the air.
