Because they are newer generation processors with integrated inverters. For example, F1 FC normally only has 2 UARTвЂ™s, while F3 and F4 can have between 3 to 5 and F7 can have 6 to 7.ДЇ3 and F7 can handle inverted signals natively, while F1 and F4 cannot.ДЇrsky SBUS and SmartPort signals are inverted at the output, the good news is F3 and F7 flight controllers can read these signals just fine. The number of UARTвЂ™s available largely depends on design of the board, and the processor used. You might not need many UARTвЂ™s, but having more is always handy.

You can assign these UART a task in the ports tab of Betaflight configurator.

For example, serial radio receivers, Telemetry, Race Transponder, VTX control etc.Д®ach UART has two pins, TX for transmitting data and RX for receiving.В Remember the TX on your peripheral connects to the RX on the FC, and vice versa.ДЇor example here are the UART3 (R3 and T3 pins) and UART6 (R6 and T6 pins) on a flight controller. UART is the hardware serial interface that allows you to connect external devices to the flight controller. UART stands for Universal Asynchronous Receiver/Transmitter. We recommend getting either an F4 or F7 flight controller, because F1 and F3 are no longer supported in the latest versions of Betaflight due to the lack of storage for the expanding firmware.ДЇC Processors: from left to right: STM32 F1, F3, F4 What is UART in Flight Controller? This article explains the differences between F1, F3, F4 and F7 MCU in more detail. The main differences being the calculation speed and memory size: The processors in FC are also known as micro controller units (MCU), they are used to store the firmware codes and handling all the complex calculations.Д¬urrently, there are 5 main types of MCU used for FCвЂ™s: F1, F3, F4, F7 and H7. вЂњ TuningвЂќ is the term we use in the multirotor hobby when changing parameters such as PID, RC rates or other settings to achieve the flight characteristics we want. Some UI looks similar, but plugging the same settings into a different FW can give very different characteristics,В so there is a learning curve when getting into a new firmware. Each firmware offers a different user interface (UI) with various parameters you can change. Modern FC firmware can be configured via a computer, smartphone, or even from your radio controller. Once you have picked your FC firmware, you can look for a compatible flight controller board. They are both closed source, and the hardware and firmware are controlled by private companies so you are limited to their own flight controllers. Other popular firmware for FPV drones are FlightOne and KISS.

It also has the widest range of flight controllers. It has the biggest user base, so you will be more likely to get help when you run into problems. The FC is also a hub for other peripherals, such as GPS, LED, Sonar sensor etc.ДЇPV drone flight controllers are rapidly evolving: becoming smaller, with more features integrated, and using better processors and hardware.Д«etaflight is open-source, developed and maintained by the community. Some FC include more advanced sensors such as Barometer (barometric pressure sensors) and magnetometer (compass). Nearly all flight controllers have basic sensors such as Gyro (Gyroscopes) and Acc (Accelerometer). Using this data, it then controls the speed of the motors to make the craft move as instructed. ItвЂ™s a circuit board with a range of sensors that detect movement of the drone, as well as user commands. The flight controller (a.k.a FC) is the brain of the aircraft. I compiled the specifications of all FCвЂ™s in this spreadsheet so you can compare them more closely If you are new to the hobby, check out our FPV drones beginners guide to learn more.
