• Built-in barometer: for accurate altitude data.

• Onboard OSD and blackbox: as listed.

• Dual BEC 5V and 10V: for a reliable power supply.

• 3-8S LiPo support: for versatile builds.

How a flight controller works

A flight controller is the brain of a multirotor or fixed-wing aircraft. It reads the gyroscope, and where fitted the accelerometer, barometer and compass, and runs a control loop that compares what the aircraft is doing with what the pilot asks for. It then sends new speed commands to the motors through the ESCs or servos many times each second. A faster processor and a better gyro allow a higher loop rate and a more locked-in feel.

Wiring and firmware decide what the board can do. The number of UARTs limits how many receivers, GPS units, telemetry radios and video systems you can connect, the PWM or motor outputs limit how many motors and servos it can drive, and the input voltage range must suit your battery and power module. Before you buy, check that the firmware you want to run supports the board and that its mounting pattern fits your frame.

Set up carefully. Flash a firmware that is listed as supported, configure the receiver protocol, set the motor order and direction, calibrate the accelerometer and, for larger aircraft, the compass, and always test with the propellers removed first. Keep the board isolated from vibration with soft mounts where the design calls for them, and never power it with a supply that is outside the rated input voltage.
