by NewBeeDrone

The NewBeeDrone Hummingbird 305 Flight Controller F722 ICM42688 with Diversity ELRS 2.4 Receiver 30x30 v1.1 is a high-performance 30.5x30.5mm autopilot designed for 5-inch to 10-inch FPV quads, long-range endurance drones, and freestyle rigs. Built around an STM32F722 MCU running at 216MHz and paired with an ICM-42688 gyro powered by an independent LDO, this flight controller ensures low-noise signal processing, clean gyro sampling, and rapid loop rates.

Featuring an integrated 2.4GHz ExpressLRS Diversity Receiver with dual MHF3 antenna ports, a TCXO temperature-compensated crystal oscillator, and onboard LNA boost, the Hummingbird 305 provides a robust long-range control link without requiring external receiver wiring. Equipped with triple independent BECs (10V 2A and dual 5V 2A rails), an onboard SPL06-001 barometer, an SD card slot for Blackbox logging, and protective nano-coating, it supports both Betaflight and iNAV firmwares for digital HD (DJI O3/O4, Walksnail, HDZero) and analog FPV setups on 3S to 8S LiPo power.

Key Features

• STM32F722 Processing Power: High-speed 216MHz F7 MCU delivers fast processing rates for complex filter algorithms and control loops.

• Integrated 2.4GHz ELRS Diversity Receiver: Onboard dual-antenna ExpressLRS receiver with LNA amplification and TCXO crystal oscillator ensures rock-solid signal reception and low latency.

• ICM-42688 Gyro with Independent LDO: Low-noise 6-axis gyro powered by a dedicated low-dropout regulator for clean gyro sampling and minimal noise interference.

• Triple Independent BEC Regulators: Delivers clean, isolated power via 10V/2A and two 5V/2A power rails for HD video transmitters, GPS, receivers, and LEDs.

• Integrated SPL06-001 Barometer: High-precision barometer enables reliable altitude hold and auto-return functionality in iNAV and Betaflight.

• Factory Protective Nano-Coating: Pre-applied protective coating guards internal circuit components against moisture, environmental debris, and wet landings.
