iFlight Borg F7 AIO 12A BL32 (FC+ESC+ELRS RX)

iFlight Borg F7 AIO with ELRS is an AIO board combining a flight controller, 4-in-1 ESC and ELRS receiver. The board is suitable for 2" drones and whoops powered by 2-4S LiPo batteries and also supports LiHV cells. The manufacturer designed it for Defender 20 Lite and Defender 20 Lite X drones, where it replaces the older F411 AIO.

The flight controller is based on an STM32F722 processor combined with an ICM42688 gyroscope. The board features an SPA06-003 barometer for altitude measurement and 16MB blackbox memory. It provides 4 UARTs and an I2C bus for connecting a GPS module with compass. Peripherals are powered by a 5V/2,5A BEC. The board can be used with both analog and digital video transmission – it has an AT7456E OSD chip. The video transmitter connects solder-free via an SH1.0 9pin connector. The board also has an integrated buzzer for locating the drone after a crash.

The integrated ELRS receiver at 2,4GHz has an antenna directly on the board, eliminating the need to mount an external antenna. Maximum telemetry power is 17mW.

The ESCs provide a maximum current of 12A and are based on an STM32G071 processor with FD6288 drivers and use BLHeli_32 firmware (target IFLIGHT BLITZ G3, rev. 32.9). They support telemetry, bidirectional DShot for RPM filtering in Betaflight, and DShot150/300/600, MultiShot and OneShot protocols. A current sensor is included. Motors connect solder-free via SH1.25 3pin connectors on the underside of the board.

Mounting hole spacing is 25,5x25,5mm M3 (M2 softmount), board dimensions are 32x32mm and weight is 6,8g. USB is routed through a SUR0.8 7pin connector.
