Flight controller HGLRC Specter 15A ELRS AIO

Order the HGLRC Specter 15A ELRS AIO flight controller - complete electronics for your micro-drone in one board

Ideal for creating ultra-compact and lightweight quadcopters flight controller HGLRC Specter 15A ELRS AIO. This is a unique All-In-One (AIO) format device. One small board contains all the key electronic components. You don't need separate controller and receiver boards. This solution radically simplifies the assembly of micro- and mini-drones. You will receive a flight-ready system with minimal weight and dimensions.

Flight controller HGLRC Specter 15A ELRS AIO is the technological heart of your tiny drone. It combines the brain, power system and communication in one module. The AIO design is ideal for Whoop-class racing drones and freestyle drones up to 3 inches. The board provides maximum performance with minimal dimensions. You can assemble an incredibly maneuverable and responsive device. This is the choice for pilots who value compactness and cleanliness of assembly.

Five main advantages of the device

• All-In-One format. Combines FC, 4 ESC and ELRS receiver in one board. This eliminates unnecessary wires and significantly reduces weight.

• Integrated ExpressLRS 2.4 GHz receiver. Provides ultra-reliable communication with a range of up to several kilometers. No need to find space for a separate receiver module.

• Built-in 4 ESC regulators 15A each. Enough to power powerful 1103-1204 motors. Ensure stable and smooth operation of the power plant.

• Compact size 25.5×25.5 mm. Ideal for the smallest Whoop and Toothpick frames. Allows you to create ultra-light and balanced drones.

• High frequency gyroscope and F4 processor. Processes data at high speed for instant response. This is necessary for technical driving and racing.

Operating principle and technical details

AIO flight controller - This is the central control hub for the entire drone. It receives radio commands from the pilot via the built-in ExpressLRS receiver. At the same time, the gyroscope and accelerometer read the drone’s orientation in space. A powerful processor (STM32F4) instantly analyzes this data.

Based on the analysis, the processor calculates the necessary adjustments. It sends control signals to the integrated ESCs. These, in turn, supply precise current to each of the four brushless motors. All this complex work happens in a split second. HGLRC Specter AIO does this consistently, providing smooth and predictable flight.
