HGLRC SPECTER F722 Lite Flight Controller w/ ICM42688P Gyro, ELRS 2.4GHz R2 RX, 16MB BB

Overview

The HGLRC SPECTER F722 Lite is a flight controller with an integrated ELRS 2.4GHz receiver (ELRS 2.4Ghz R2) in a compact 28×28mm / 20×20mm M3 mounting format. It uses an STM32F722 MCU and ICM42688P gyroscope, supports OSD, and is designed to reduce wiring and installation space with a 4g ultra-lightweight build.

Key Features

• Onboard ELRS 2.4GHz receiver; external receiver connection is also supported (same serial port as external receiver).
• F722 main control: double-precision floating point acceleration, millisecond-level flight command processing, supports high-frequency PID refresh.
• Wide input voltage range: 8.4V-26.1V (2-6S LiPo).
• Integrated BEC: 5V 2A.
• Black box: 16MB.
• 5 serial UARTs.
• Support 5V/BAT voltage output for compatibility with most analog/HD VTX.
