Product overview
The RadioLink F722 Racing Master is a flight controller for racing and other multirotor builds using Betaflight or INAV. Its electronics combine an STM32F722RET6 processor, an ICM42688/ST LSM6DSK320X gyroscope, a BMP280 barometer and 128MB of Black Box storage. An MPS MP2491C switching power supply and built-in 3.3V/4.5V/5V/12V BEC outputs support peripheral integration. The controller provides up to eight output channels for 2-8 axis multirotors, including X8 configurations, and supports two-way DShot, OneShot and PWM signals alongside ESC telemetry.
Physical integration uses both sockets and solder pads, giving builders alternative connection points for external equipment. Dedicated ports cover two ESC connections, a camera, receiver, GPS, DJI digital video transmission and analog video transmission. A six-pin socket serves DJI HD equipment, while a four-pin VOUT socket serves analog video connections; DJI and CADDX HD digital video transmission are supported as plug-and-play connections. Solder pads also accommodate a buzzer and LED strip. A configurable switch can turn the 12V BEC video transmission supply on or off.
The supplied configuration consists of one F722 controller, connection cables and a package box, rather than a complete flight platform or airframe kit. The cable set includes two ESC cables plus one longer ESC cable, camera and analog video cables, a GPS cable, and ELRS, R8SM and general receiver cables. Integrated OSD provides graphical flight information without an external OSD module, including navigation, electrical and control information. Parameter adjustment and firmware upgrades are supported through Betaflight or INAV Configurator on a PC or mobile phone.
