Detail

This device uses an upgraded F405 flight controller chip that offers better performance than F411, equipped with an internal Bluetooth chip for seamless wireless Betaflight setup. The board comes with a 4-level battery voltage indicator and an internal barometer, supporting connections to all DJI Air Units. It features 4 available UART ports and a dual BEC setup with 5V 2A and 9V 3A outputs. 35A 4-in-1 BLHeliS Mini ESC: This ESC provides four synchronized outputs with 35A continuous current, offering powerful power for operating all 2-4 inch and light 5-inch quadcopters through 4-6S batteries. It is equipped with a built-in TVS transient voltage suppression diode to better absorb overvoltage and provides advanced protection for the ESC.
