Features: Upgrade NAZE32 SP Racing F3 Flight Control With Integrated OSD for Multicopter The SPR F3 builds on tried and tested software, processor and sensor technology to make your aircraft fly like it's on rails. ST debug port on the back of the board have (SWD) and startup mode selection, not deadlock bootloader. There MEGA328 ISP port on the back of the board, will not deadlock bootloader. looptime up to about 2 times the previous generation based stm32F1 flight control. No-Compromise I/O Use all the features all the time; e.g. Connect your OSD + SmartPort + SBus + GPS + LED Strip + Battery Monitoring + Sonar + 8 motors - all at the same time. Configurable The SP F3 runs Cleanflight which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux). Tiny and lightweight Flight Logging On-board high-capacity black box flight log recorder - optimize your tuning and see the results of your setup without guesswork. New Generation CPU STM32 F3 support next-generation processor Attitude efficient hardware floating-point operations, and faster ARM Cortex M4 core computing. All using 2.54 interface. PDB can be more perfect combination. Full support for OneShot ESCs for easy PID tuning and a sharper response. Broad RC receiver Support Supports SBus, SumH, SumD, Spektrum1024/2048, XBus, PPM, PWM receivers. No external inverters required (built-in). Programmable LED Dedicated output for programmable LEDs - great for orientation, racing and night flying. Battery monitoring ports for voltage and current. Sonar support for precision low-altitude hold. I2C port always powered, perfect for external sensors or always-on OLED Screen. Buzzer port for ble warnings and notification F3 + OSD run the company to modify the optimization of cleanflight flight control software (FC).
