features a built-in Bluetooth chip for seamless wireless Betaflight tuning.

The board comes with a 4-level battery voltage display, built-in barometer, and supports connectivity to all DJI Air Units. It offers 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 a continuous current of 35A, delivering strong power to drive all 2-4 inch and lightweight 5-inch quadcopters via 4-6S battery. Equipped with a TVS transient suppression diode onboard, it better absorbs surge voltage, providing enhanced protection for the ESC.
