Mamba MK4 F722 APP is a high quality flight controller with F722 processor and MPU6000 gyro. The fourth generation MK4 has larger solder pads for easier soldering. The board includes a barometer, I2C pads for compass connections, 16MB of blackbox memory and both 5V and 9V 3A BECs. The board has 8 motor outputs so it can be used on X8 Cinelifters as well. The integrated Wifi is also a pleasure. You can connect wirelessly to the controller, for example via phone and Speedybee app and thus set up the board conveniently even in the meadow. To protect the board from voltage spikes, a TVS diode is integrated on the board.
