Flight Controller

A flight controller (FC) is a small circuit board of varying complexity. Its function is to direct the RPM of each motor in response to input. A command from the pilot for the multi-rotor to move forward is fed into the flight controller, which determines how to manipulate the motors accordingly.

Pixhawk 4 flight controller

Pixhawk 4 is the latest update to the successful family of Pixhawk flight controllers. It was optimized to run the full Dronecode stack, and comes pre-installed with the latest PX4 firmware. It features the latest advanced processor technology from STMicroelectronics, sensor technology from Bosch and InvenSense, and a NuttX real-time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.

Highlighted Features

  • Main FMU Processor: STM32F765, 32 Bit Arm Cortex-M7, 216MHz, 2MB memory, 512KB RAM
  • GPS: ublox Neo-M8N GPS/GLONASS receiver; integrated magnetometer IST8310
  • Operating temperature: -40 ~ 85°c
  • On-board sensors: Accel/Gyro- ICM-20689, Accel/Gyro- BMI055, Mag- IST8310, Barometer- MS5611

Pixhawk 4 mini is based on the Pixhawk FMUv5 design standard and is optimized to run PX4 flight control software.The Pixhawk 4 Mini autopilot is designed for engineers and hobbyists who are looking to tap into the power of Pixhawk 4 but are working with smaller drones. Pixhawk 4 Mini takes the FMU processor and memory resources from the Pixhawk 4 while eliminating normally unused interfaces. This allows the Pixhawk 4 Mini to be small enough to fit in a 250mm racer drone. The Pixhawk 4 Mini is easy to install; 2.54mm (0.1in) pitch connector makes it easier to connect the 8 PWM outputs to commercially available ESCs.
