Clean Gyroscope Power Supply, Smoother Flight
Equipped with the renowned brand MaxLinear's LDO power supply chip, the gyroscope receives independent power, boosting surge protection capacity by 320%. Additionally, built with a 100uF ultra-large filtering tantalum capacitor, guarding the gyroscope's data from interference caused by the power source. Each posture and movement during flight receives precise responsiveness, allowing you to fully experience the pure beauty 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 goggles to check the battery status.
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, go to the App > Motors > Motor Direction Settings.
Support DJI Digital Video Transmitter
The flight controller has two independent 9V 3A BEC and 5V 2A BEC, supports various analog image transmissions above 5V, and also supports DJI O3 Air Unit/Link / Vista/Air Unit V1
M2 or M3? Why not both?
Have you ever experienced that the stack holes of your frame did not fit the stack you got? This stack is perfectly compatible with M2/M3 screws. What’s more, two sets of M2 and M3 screws + silicone grommets are included in the package!
