Borg G4 1S AIO ELRS 2.4G By Iflight

The Borg G4 1S AIO with Rx from iFlight is an all-in-one unit (FC + ESC + 2.4 GHz ELRS receiver) specially designed for 65–75 mm Whoops, combining high performance with seamless integration.

Powered by an STM32G473, it delivers greater processing power than the STM32F411, ensuring more responsive and precise control. The flight controller features an ICM42688 gyro, AT7456E OSD, and 16 MB of Flash memory for Blackbox logging, along with a 5 V 3 A BEC.

The ESC is designed exclusively for 1S power, supports a continuous current of 12 A, and is compatible with protocols such as DShot150/300/600, MultiShot, and OneShot. The built-in ELRS receiver provides direct connectivity, while still allowing the use of an external receiver if preferred.

Its compact size, 25.5×25.5 mm mounting pattern with 3 mm holes, and ultra-lightweight design (~4 g) make it an ideal choice for performance-oriented builds where every gram matters.
