Hardware
The SF Racing F3 flight controller is designed to provide high performance flight experience for
the hobbyists. With verified sensor algorithm, it provides incomparable I/O capabilities. The SF
Racing F3 runs a next-generation 32-bit STM32F303CCT6 processor, an MPU6050 accelerometer
and a gyroscope sensor, all high integrated on a lightweight PCB to improve the flight
performance. In addition, it offers more practical functions to your aircraft. The SF Racing F3 flight
controller is perfect whether you are doing FPV contest or practicing stunt flying and it is suitable
for a variety of aircrafts including tricopters, quadcopters, hexacopters, octocopters, fixed wing
aircrafts, etc.
Features
1. The next-generation processor STM32F3 supports high performance floating-point arithmetic
and faster calculation by the ARM Cortex M4 kernel. The looptime for the flight controller is about
2 times of the previous STM32F1.
2. The functions of the I/O ports in the flight controller can be greatly extended and these ports
can be used simultaneously for connecting various devices such as OSD, Smartport, SBUS, GPS,
LED light strip, battery monitor, buzzer, and eight motors.
3. The sixteen PWM I/O cables serve for ESCs, servos and traditional receivers, among which eight
cables work with standard pin headers and the others are distributed in the connectors of the
flight controller.
4. It supports SBUS, SFektrum1024/2048, PPM, PWM and XBus receivers and needs no external
inverter with one already built in.
5. It fully supports the OneShot ESCs for easy PID tuning.
6. The dedicated programmable LED light strip provides a variety of signal lights for the aircraft
heading, racing and night flight.
7. It includes a specific I2C port to connect an OLED display, needless of extra batteries.
8. It provides a battery monitoring port for voltage and current.
9. The buzzer raises the alarm and sends out notification so you can search for the lost aircraft.
10. You can choose from serial wire debug (SWD) and boot mode, so the bootloader will not be
locked.
