The Foxeer F722 V4 is a good FC in mini size. Unlike other FCs, this FC supports up to 8S batteries. This has advantages even when powered by a classic 6S battery, as the electronics are more resistant to voltage peaks. The Foxeer F722 uses a powerful F7 processor in combination with an ICM 42688-P gyro, which has a refresh rate of 8kHz. 5V/3A and 10V/2A BEC, 16MB memory for blackbox are available on the board. The board also has I2C pads for connecting a compass and 8 outputs for motors. OSD for analog video and support for all digital video transmitters is a matter of course.
