Description

The SP Racing F3 ACRO Flight Controller is a compact, feature-rich board engineered for competitive FPV racing. Its STM32F303 processor, operating at 72MHz with a floating-point unit (FPU), enables faster loop times and more efficient flight calculations compared to previous-generation F1 boards. This allows pilots to run advanced features simultaneously without performance degradation.

Built on the proven Cleanflight ecosystem, the controller offers extensive connectivity including a dedicated I2C port, buzzer output, sonar input, and programmable LED strip support. Its integrated OSD eliminates the need for an external module, saving weight and simplifying builds. The board’s 36x36mm mounting pattern makes it compatible with a wide range of mini quadcopter frames.

Key Features

  • High-performance STM32F303 ARM Cortex-M4 core with integrated math co-processor (FPU).
  • On-board OSD for battery voltage, flight timer, RSSI, and other critical telemetry data.
  • Direct support for SBus, SumH, Spektrum, XBus, PPM, and PWM receivers without external inverters.
  • Dedicated output for multi-colored LED strips for orientation and night flying.
  • Developer-friendly SWD debugging port and unbreakable bootloader for firmware updates.
  • Compact 36x36x5mm footprint (without shell) and lightweight 5.9g board weight.
  • Comprehensive I/O for connecting GPS, sonar, battery monitor, and up to 8 motors.

Applications

  • 5-inch and 6-inch FPV racing quadcopters requiring a lightweight, high-performance flight controller.
  • Freestyle drone builds where integrated OSD and extensive I/O simplify wiring and setup.
  • Mini quadcopters utilizing Cleanflight or Betaflight firmware for acrobatic and line-of-sight flying.
  • FPV drone builds needing direct support for FrSky SmartPort telemetry and LED strips for orientation.

Frequently Asked Questions

What firmware does the SP Racing F3 ACRO controller run?

The SP Racing F3 ACRO is designed to run Cleanflight firmware, which is configurable via a cross-platform GUI on Windows, macOS, or Linux. It provides extensive tuning options for PID controllers, rates, and features like Oneshot and Dshot for ESC control.

What is the input voltage for this flight controller?

The board requires a regulated 5VDC input. This is typically supplied from a BEC (Battery Eliminator Circuit) on your ESC or a separate voltage regulator. Do not apply direct LiPo battery voltage to the board's 5V input pins.

Does it support FrSky SmartPort telemetry?

Yes, the SP Racing F3 has dedicated I/O capabilities that support FrSky SmartPort telemetry when connected to a compatible receiver. This allows you to transmit battery voltage, RSSI, and other flight data back to your transmitter without an external converter.

What receiver protocols are supported?

It natively supports a wide range of protocols including SBus, SumH, SumD, Spektrum 1024/2048, XBus, PPM, and standard PWM. Built-in signal inverters mean no external hardware is needed for SBus or other inverted serial protocols.
