Main Features


Configure your FC and ESC via Bluetooth! With SpeedyBee app, turn your phone into an all-in-one FC configurator and tune your quad anytime, anywhere.	ESC upgraded to 55A with heat sink The PCB design has been refined, with copper thickness increased from 2 to 3 ounces and enhanced MOSFET specifications. Continuous current now reaches 220A across all channels, peaking at 280A for 10 seconds. An added aluminum alloy heat sink ensures efficient MOSFET heat dissipation for stable ESC output. It delivers a genuine 55A output, primed for your baddest high-powered 6S motors.	ICM42688P Gyro and clean power supply Featuring MaxLinear's esteemed LDO power chip, the gyroscope gets dedicated power, enhancing surge protection by 320%. A 100uF filtering tantalum capacitor shields gyro data from power interferences. This ensures precise flight responsiveness, letting you truly savor the joy of flying!


Built-in LED Battery Indicator Built with a 4-level LED battery indicator, now you can fly anywhere without worry even without your lipo checker!	SD card compatibility issue fixed! The F405 V3 FC faced compatibility issues with certain microSD cards,d with a few even occasionally affecting the stable OSD display. The improved F405 V4 flight controller, however, addresses these challenges. It reliably supports C4, C6, C10, and higher cards at 2k/4k logging rates. BF/INAV can recognize up to 4GB of black box space. Once you clear the SD card, you can enjoy 1000+ flights. Experience black box freedom like never before!	Change motor directions wirelessly! Are you still using a computer to change motor directions? With this stack, when you finish your build, connect to the SpeedyBee app, change the motor directions just in a few simple steps*. Then take off and use this feature, please go to the App > Motors > Motor Direction Settings.


8 motors output for X8/Y6/fixed wings. You could use this stack to build your X8 drones, Y6 drones or fixed wings. Forget about crawling through your massive build just to plug in that USB cable. Just take out your phone to configure everything in the SpeedyBee app.	4 sets of LED pads with simple switching. Need more visibility at night? Just solder up your LED strips* and blaze the darkest trail you can find. With just one tap on the BOOT button, you can cycle through all different LED presets and pick the one you love!	TVS Protective Diode + 21 Onboard TDK Capacitors+1000uF HighCapacity Electrolytic Capacitor = Upgraded ESC Protection We've included a TVS diode that effectively absorbs voltage spikes during power-up and crash events. The board features 21 high-quality Japanese TDK 35V 22uF SMD filtering and energy storage capacitors. These, along with the standard 1000uF high-frequency, low-ESR electrolytic capacitor, effectively filter out signal interference from the power supply to the flight controller's gyroscope, ensuring smoother flight performance.

And packaged with more usefulfeatures. Built-in barometer for accurate height calculation SD card slot can support up to 4GB Blackbox data* Dedicated DJI Air Unit connector for a quick digital build 5V & 9V Dual BECs now upgraded to both 3A output 4x UARTs for your receiver +VTX+camera+GPS Power your GPS with a USB cable - no battery needed, No extra heat, no worries 22mm cutouts for FPV camera in your tight build	Importance notice for SBUS receiver When using an SBUS receiver, the SBUS signal wire of the receiver must be connected to the SBUS pad on the front side of the flight controller (this pad internally uses UART2).If you are also using the DJI Air Unit(O3/Link/Vista/Air Unit V1), you will need to disconnect the SBUS signal wire from the Air Unit harness. Failure to do so will prevent the SBUS receiver from being properly recognized by the flight controller. You can use tweezers to pick out the SBUS wire from the 6-pin harness connector (or directly cut this wire) and insulate the exposed part of the wire carefully.	Importance notice for ELRS receiver We recommend connecting the ELRS receiver's TX and RX to the T2 and R2 pads on the flight controller. However, when using the DJI Air Unit simultaneously, some ELRS receivers may not be recognized properly by the flight controller. If you encounter this issue, you need to disconnect the SBUS signal wire from the Air Unit harness. You can use tweezers to pick out the SBUS wire from the 6-pin harness connector (or directly cut this wire) and insulate the exposed part of the wire carefully.
