NewBeeDrone Hummingbird 200 AT32F435 with ELRS

Hummingbird 200 RaceSpec is a flight controller with an integrated 2.4GHz ELRS receiver. The board features a 20×20 mm mounting pattern and is designed primarily for 5" racing drones powered by 3–6S LiPo batteries.

The controller is built around an AT32F435 processor and an ICM42688 gyro. It includes an OSD chip for analog video and a connector for HDZero or DJI O4 video transmitters. Two independent BEC outputs (10V/2A and 5V/2A) provide power for peripherals. The integrated ELRS receiver with dual ceramic antennas and a TCXO oscillator ensures a stable RC link and simplifies the drone build. The board supports Betaflight firmware and features UART and I2C interfaces for connecting GPS, LEDs, or a compass. With its durable construction, clean layout, and low weight of 4.7 g, the Hummingbird 200 RaceSpec is an ideal choice for racing FPV drones where fast response and simple installation are key. The board is factory-coated with a nano coating for moisture protection.
