Hummingbird 305 Flight Controller F722 ICM42688 with Diversity ELRS 2.4 Receiver 30x30 v1.1

Now Hummingbird 305 Flight controller v1.1 comes with u.fl connector for the onborad ELRS Receiver.

The Hummingbird 305 Flight Controller F722 ICM42688 with Diversity ELRS 2.4 Receiver 30x30 v1.1 is a high-performance flight controller tailored for 5” and larger builds, offering cutting-edge processing, integrated diversity ExpressLRS receiver, and compatibility with both Betaflight and iNAV firmware.

At the heart of the board is the STM32F722 MCU running at 216MHz, delivering exceptional responsiveness for advanced control algorithms. Paired with the industry-recommended ICM-42688 gyro powered by its own independent LDO, the flight controller ensures ultra-clean signal acquisition and minimal noise.

Designed with triple independent BECs — 10V 2A and dual 5V 2A regulators — the board provides stable and reliable power for your HD VTX, GPS, LEDs, and other peripherals. It also includes the high-precision SPL06-001 barometer and a TCXO oscillator for improved GPS lock and stable sensor readings in extreme environments.

One of the biggest highlights is the integrated 2.4GHz ExpressLRS Diversity Receiver, featuring dual antennas and onboard LNA boost. Enjoy rock-solid control link quality with reduced latency, maximum signal integrity, and less wiring hassle.

Whether you’re flying analog or digital, the Hummingbird 305 has you covered. Analog pilots benefit from the built-in NBD7456 chip for OSD, while digital users will appreciate the plug-and-play support for DJI FPV systems via UART4.
