SF Racing F3 flight controller
About the SF Racing F3
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 MPU6500 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 SFecific I2C port to connect an OLED diSFlay, 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. 11. It uses pin headers, JST-SH sockets or solder pads to wire up. Both angled and straight pin headers are available. 12. It works with a variety of aircrafts like tricopters, quadcopters, hexacopters, octocopters, planes, etc. 13. Configuration of the flight controller can be done via a cross-platform GUI (Windows/OSX/Linux).
