Advanced Flight Control System: The GHF411 AIO-HD integrates the STM32F411 MCU and -42688-P gyro for superior flight stability. It features a comprehensive suite of onboard systems including a 5V/2.5A and 10V/2A BEC, OSD (AT7456E), barometer, and a 16MB black box for enhanced flight data recording. Robust ESC Integration: Equipped with a 40A ESC using Blheli_S firmware, this flight controller supports Dshot150, Dshot300, and Dshot600 for precise motor control. The ESC's EFM8BB21 MCU ensures reliable performance, complemented by a built-in module for added protection. Comprehensive Connectivity: Supports multiple receiver protocols including ELRS, TBS, SBUS, IBUS, DSM2, and DSMX. It also features GPS, compass, and HD O3 capabilities, making it versatile for drone builds. Connectivity is further enhanced with UART, Softserial, and IIC interfaces. Additional Features: The board includes a micro-USB port, current and voltage sensors, a DFU button for firmware updates, and provisions for LED strips and buzzers. The compact design measures 33x33MM with mounting holes for easy installation.
