What is BB on flight controller?

Most flight controllers have dedicated solder pads for connecting the buzzer, normally labelled as B+ / Buzzer+ and B- / Buzzer-. Simply solder the red wire or longer pin to the Buzzer+ pad on the FC, and solder the black wire or shorter pin to the Buzzer- pad on the FC.

What is VCC on a flight controller?

VCC is Voltage Common Collector. Think of it like your LIPO Battery Source Voltage. The FC likes to have VCC from the Battery so it can read the voltage of the battery and report that on OSD.

What is FPV range?

The video quality will become grainy or you will lose video as the receiver and transmitter move away from each other. Using the above omnidirectional transmitter and corresponding antenna will give a live video signal up to about 1.5 mile (2.4 km) range.

What is FCU drone?

product: • A Flight Controller Unit (FCU) to manage flight under different conditions, relying on its Inertial. Measurement Unit (IMU) to stabilize drone hovering. In professional drones, the FCU embeds a. GPS (Global Positioning System) to form an Autopilot System.

What is UART FC?

What is UART in Flight Controller? UART stands for Universal Asynchronous Receiver/Transmitter. UART is the hardware serial interface that allows you to connect external devices to the flight controller. For example, serial radio receivers, Telemetry, Race Transponder, VTX control etc.

What is NC on flight controller?

NC stands for not connected. GND is for the ground connection to your flight controller.

What are the 4 different types of drones?

Here’s a rundown of the four main types of drones, their uses, their strengths and weaknesses:

• Multi-Rotor Drones.
• Fixed-Wing Drones.
• Single-Rotor Drones.
• Fixed-Wing Hybrid VTOL.

What are the uses of drone?

Drones are now also used in a range of civilian roles, including the following:

• search and rescue.
• surveillance.
• traffic monitoring.
• weather monitoring.
• firefighting.

What is Class C airspace?

Class C airspace is generally airspace from the surface to 4,000 feet above the airport elevation (charted in MSL) surrounding those airports that have an operational control tower, are serviced by a radar approach control, and have a certain number of IFR operations or passenger enplanements.

What is UART inversion?

UART inversion means that the data has been inverted. If you think of the data as zeros and ones, a normal signal could look like 01000101 11010110. When that signal is inverted, it would look like 10111010 00101001. As you can imagine, these devices will not be able to understand each other.

What is ESC telemetry?

The ESC telemetry is feature that allows you to display data from your Electronic Speed Controller (ESC) directly in the transmitter. Depending on transmitter capabilities you can Log the values and use them for a various purposes. The ESC telemetry is mediated through the Spirit units (firmware v2.

What is thrust of a motor?

The thrust-to-weight ratio is used to actually compare engines is the number found when the engine is first running. Thrust is measured in “pounds of thrust” in the U.S. and in Newtons in the metric system. 4.45 Newtons of thrust equals 1 pound of thrust.
