Redfox A3 F722 45A AIO Flight Controller.
Introducing the Redfox A3 series flight controller, a new choice in lightweight FPV drones brought to you by the Sub250 team.
Designed specifically for 2 to 3.5-inch drones, it integrates the powerful computational capabilities of the F722 MCU to ensure exceptional flight performance.
Featuring an independently designed Type-C adapter board, it can be conveniently placed at any location on the frame for quick parameter adjustments.
Onboard DJI 6-Pin interface, offering direct connectivity to digital video transmission systems.
Equipped with four sets of UART ports, providing more possibilities for installation and upgrades. It also comes with a 5V@2.5A BEC to meet the increasing demand for additional peripherals.
Sub250 is committed to combining “lightweight” and “high performance” to bring a brand new experience to the racing drone field. The Redfox A3 series flight controller helps you explore the perfect fusion of lightweight design and exceptional performance.
