V4 Features:
1. The new V4 stack circuit design has been significantly optimized, with PCB copper thickness upgraded from 2 ounces to 3 ounces, and MOS transistors upgraded to higher specifications. The continuous current of a single circuit has been upgraded to a total of four circuits of 220A, and the peak current has been further increased to 280A for 10 seconds.
2. Easily drive any of the most violent 6S motors. Add aluminum alloy heat dissipation fins to quickly evacuate MOS tube heat, making the output of the electrical regulator more stable.
3. Using well-known brand power supply chips to independently power the onboard ICM42688P gyroscope, the anti surge capability is increased by 320%; Equipped with a 100uF ultra large filtering tantalum capacitor, it protects the gyroscope data from power interference and allows you to fully experience the pure beauty of flight!
4. The F405 V4 flight control supports 8-way motors, so it can be used on your X8, Y6, fixed wing, and other models that require more than 4 motors. Now open the SpeedyBee app and adjust the parameters immediately.
5. We suggest connecting the TX and RX of the EL RS receiver to the T2 and R2 of the flight control. When you both When using for DJI sky terminal, some ELRS receivers may not be able to be recognized by flight control normally. If this problem occurs, you need to connect the SBUS signal cable of the sky end cable Disconnect from flight control. You can use tweezers to pick out the SBUS cable head from the 6PIN cable terminal (Alternatively, cut the wire directly) and properly insulate the wire ends.
