With SpeedyBee app, turn your phone into an all-in-one FC configurator and tune your quad anytime, anywhere. Enjoy wireless, fully configurable ESC experience with SpeedyBee app 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! Forgot your LiPo checker? Just look at the FC! On the side of the flight controller, you will find a 4-level battery capacity indicator. As soon as you connect the battery, you can instantly see the battery level, saving you the hassle of needing to put on glasses to check the battery status. SD card compatibility issue fixed! The F405 V3 FC faced compatibility issues with certain microSD cards, 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. * To 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! * LED strips could be purchased here **Or long press the boot button to switch to Betaflight LED mode. TVS Protective Diode 21 Onboard TDK Capacitors 1000uF High-Capacity 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 useful features. ● 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 ● 4 x 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
