NewBeeDrone Hummingbird 200 RaceSpec AT32F435 20x20 FC with ELRS 2.4GHz

The Hummingbird 200 RaceSpec is a 20x20 flight controller built for 5-inch FPV racing. It pairs an AT32F435 processor with an onboard ExpressLRS 2.4GHz receiver, so there is no separate receiver to mount, wire or protect. It runs Betaflight on 3-6S LiPo. This is the flight controller only: the ESC is sold separately.

Key features

• AT32F435 MCU at 288MHz, with an ICM-42688 gyro powered by its own dedicated LDO for a clean signal
• Built-in UART ExpressLRS 2.4GHz receiver on UART1, with dual ceramic antennas and a TCXO oscillator
• Two independent BECs: 10V 2A for the video transmitter and 5V 2A for peripherals
• Plug-and-play UART5 port for a DJI O3/O4 or HDZero VTX, plus a spare UART7 and LED and I2C pads
• NBD7456 analog OSD chip and a nano-coated board
• Grommet mounting on a 20x20 pattern, with holes for M2 or M3 screws

The receiver runs NewBeeDrone's own ExpressLRS-based firmware, so flash and bind it using the NewBeeDrone Diversity 2.4GHz RX V2 target. A 36 mm 8-pin cable is included for the ESC connection, but check that your ESC's pinout matches before you plug it in. The board has no buzzer output, so fit a standalone lost-model alarm if you want one.
