Buy for $60

Compatible with fixed-wing drones, if you provide an external 5v BEC to power the servos.

ExpressLRS (ELRS) receiver and antenna

With onboard ELRS, you no longer need to buy and mount a separate receiver. Includes a dedicated ELRS chip - this can always run the latest version of ELRS. Comes installed with ELRS 3.0. This is not SPI ELRS!

Plug + play with popular ESCs, and DJI O3.

Its included cable connect directly to Diatone ESCs. Also includes a cable with separate header you can wire into other configs. Includes cables for digital VTXes, and is compatible with DJI's O3 cable.

Easy to use

Easy and fast to connect, with clearly-labeled connectors and cables for ESC, and Vtx/camera. Uses a sturdy GH header for the ESC. Big solder pads are included as well. The included ELRS radio means one fewer device to connect.

Works with Betaflight

Suitable for full-size quads, and whoops. The 30mm mounting holes are on break-off tabs, for mounting on small frames.

Includes DJI-digital compatible pin header

Does not include analog OSD support - this is a digital-only FC. Includes a transient voltage suppressor to provide dedicated, safe power to your Vtx and camera.

Compatible with DJI Air Unit, Caddx Vista, DJI O3, HDZero, and Walksnail. The included cable is compatible with the connector on DJI O3.

Includes a TVS diode, which blocks voltage spikes

The FC circuitry and attached hardware like VTXs are protected from transient battery voltage spikes. If more than 26V reaches the FC from the battery, current is immediately blocked until voltage is back to a safe level.

Compatible with DJI and HDZero digital systems

With onboard ELRS, you no longer need to buy and mount a separate receiver. Features lower latency than offboard receivers due to a direct connection with the FC computer.

Compatible with DSHOT-600, and bidirectional DSHOT-300

Onboard altimeter (barometer), and 16MB black box flash memory

Features robust power filtering and separation, to reduce interference, and provide smooth sensor readings and control response.

Includes anti-vibration rubber dampers
