Product overview

The iFlight Borg Mini F7 (RX) flight controller is a Mach R3 accessory for recreational racing applications. Its STM32F722RET6 processor works with an ICM42688 gyroscope, SPA06-003 barometer and AT7456E analog OSD, with 16 MB of blackbox storage. The board measures 34 × 28.5 mm ±1, weighs 6.8 g ±1 and uses a 20 × 20, φ4 mounting pattern. It supports 4–8S input and LiHV batteries, provides outputs for four motors and runs IFLIGHT_BLITZ_F722 firmware for Betaflight.

An onboard ELRS 2.4 GHz receiver integrates an ESP8285 MCU, SX1281 RF chip and temperature-compensated crystal oscillator, with 17 mW (12.3 dBm) telemetry power. Six UARTs provide connections for video transmission, the integrated receiver, GPS or other serial devices, and ESC telemetry. Peripheral support includes I2C, LED strips and a buzzer, alongside DJI MSP, Smartaudio, IRCTramp and HDZero protocols. BEC outputs supply 5 V at 2.5 A and 12 V at 2 A, with a VTX switch on the 12 V output. Autonomous flight is not supported. The package contains one Mach R3 dedicated accessory.
